[Scilab-Dev] Compiling Scilab for macOS

Sun Apr 19 15:33:13 CEST 2020

hi again, 

great, some progress... after remove ant, no different, but after remove all java version except 1.8, i get following error instead:

    [javac] /Users/kennethkoh/scilab-6.1/scilab/modules/graphic_objects/src/java/org/scilab/modules/graphic_objects/datatip/Datatip.java:35: error: cannot access UserDefinedFormat

    [javac] import org.scilab.forge.scirenderer.ruler.graduations.UserDefinedFormat;

    [javac]                                                      ^

    [javac]   bad class file: /Users/kennethkoh/scilab-6.1/scilab/modules/scirenderer/jar/scirenderer.jar(org/scilab/forge/scirenderer/ruler/graduations/UserDefinedFormat.class)

    [javac]     class file has wrong version 57.0, should be 52.0

    [javac]     Please remove or make sure it appears in the correct subdirectory of the classpath.

will explore more later.

I do always make clean before a new build  for this case, i even git another scilab to make sure it is really clean.

However  i did not uninstall the ant and java, will give a try again and get back to you. 

Thanks alot

Rgds,

Hello,

Did you a make clean ? Did you completely uninstall all brew ant versions ? I know this should not be necessary but did you uninstall openjdk at 13 ?

As I had start with brew, so I just tried to cont using the brew before I switch to fink if no success, and in fact, I get the similar error:

        ^

Do correct me If I did anything wrong, my steps to reach here:

1. git scilab master

2. svn checkout pre-requisite as describe in https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/wiki.scilab.org/Compiling%20Scilab%20under%20MacOSX#preview

3. patch change #21438 

4. manual install ant:

Java Configuration:

  JAVA_HOME ........... = 

  JAVAC ............... = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/javac

  JAVA_CLASSPATH ...... = 

  JAVA_VERSION ........ = 1.8

  JAVAC_FLAGS ......... = -g

  JAVA_JNI_INCLUDE .... = -I/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/include -I/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/include/darwin

  JAVA_JNI_LIBS ....... = -framework JavaVM

  JAVA_JNI_LIBS_PRELOAD = 

  JAVA ................ = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/java

  JAVADOC ............. = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/javadoc

  JAR ................. = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/jar

  ANT ................. = /Users/kennethkoh/Downloads/apache-ant-1.10.7/bin/ant

5. Get the jogl2.4 from rc. I am not sure this step is correct, but i just download 3 xz files, unzip them, and copy jogl-all.jar and glugen-rt.jar and replace in scilab thirdparty folder jogl2.jar and glugen2-rt.jar. 

checking jogl2...  /Users/kennethkoh/scilab-6.1/scilab/thirdparty/jogl2.jar 2.4 

Check of the presence of libjogl.jnilib and libjogl_awt.jnilib disabled under Mac OS X

checking gluegen2-rt...  /Users/kennethkoh/scilab-6.1/scilab/thirdparty/gluegen2-rt.jar 2.4 

6. Then I get the error as mentioned above. 

Any advice on this, or I shall try on the fink next.

thanks again.

Chin Luh

Hi,

You are right Stephane! Ant was in fact causing the problem here.

My workaround was:

brew install ant at 1.9

Trying to build with clang right now.

Cheers,

Arvid

Hello,

That's one of the reasons why I don't like Homebrew: thos packaging system is quite aggressive w.r.t. software versions. I think The problem you have here is due to the Ant package, whose version needs openjdk13. Hence, all java builds within Scilab are
 done with java13. The only workaround I found is to uninstall the Ant Homebrew package and manually installed official build of 1.10.7 version built above JDK  1.8 (https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/ant.apache.org/bindownload.cgi).

My personnal setup to build Scilab 6.1 OSX version is

- OX HighSierra or Mojave

- Fink 0.45 as a packaging system, which is more conservative w.r.t. library versions

- Jogl >= 2.3.2 patch (https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/codereview.scilab.org/#/c/21438/)

- jogl 2.4 (pick up the lastest release candidate at https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/jogamp.org/deployment/archive/rc/). jogl 2.4. is absolutely needed (see https://antispam.utc.fr/proxy/1/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/forum.jogamp.org/JOGL-on-Mojave-Mac-OS-10-14-td4039037.html), I had to build official 6.0.2 version above it.

On Catalina and latest XCode you can try to build with bundled clang which is now C++17 compliant. However, in order to build for Mojave and before, you cannot uses c++17 features.

I personnaly build Scilab under Mojave and HighSierra with the folowing configure flags :

 ./config.status --config
 '--without-openmp' '--without-tk' '--with-eigen_include=/Users/mottelet/git/scilab_master/scilab/lib/Eigen/includes' 'F77=gfortran-fsf-8' 'CC=gcc-fsf-8' 'LDFLAGS=-L/sw/lib/gcc8/lib/' 'CXX=g++-fsf-8' 'LIBS=-lstdc++fs'
console module has to be built separately with clang: cd modules/console make CC=clang. Imposing CC=clang globally is not recommended for exception handling between e.g. fortran/C/C++

If you manage to obtain a successful build, then you will encounter the link ordre problem. That's where I am stuck now. However, using https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/codereview.scilab.org/#/c/21211/ will allow you to use Scilab in -nw mode without any problem. But in the full GUI mode, clc, tohome, prompt are broken (no crash, just the message "This feature
 has not been implemented in this mode").

Tell me when you will be arrived at this point...

Hi Samuel, 

Thanks for your reply. Yes, there are 2 version of Java, another is 13, but in fact, i already use the export JAVA_HOME before "make":

Kenneths-MacBook-Air-2:scilab kennethkoh$ java -version

openjdk version "1.8.0_242"

OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_242-b08)

OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.242-b08, mixed mode)

Kenneths-MacBook-Air-2:scilab kennethkoh$ javac -version

javac 1.8.0_242

and also the configured show below:

checking JAVA_HOME variable... JAVA_HOME variable found, use it as JVM root directory

checking for zip or jar files to include on CLASSPATH... 

checking to see if the java compiler works... yes

Using JAVAC=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/javac

Java found in /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

checking type of jvm... jdk

checking java API version... 1.8

Using the following JNI include flags -I/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/include -I/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/include/darwin

Java Configuration:

  JAVA_HOME ........... = 

  JAVAC ............... = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/javac

  JAVA_CLASSPATH ...... = 

  JAVA_VERSION ........ = 1.8

  JAVAC_FLAGS ......... = -g

  JAVA_JNI_INCLUDE .... = -I/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/include -I/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/include/darwin

  JAVA_JNI_LIBS ....... = -framework JavaVM

  JAVA_JNI_LIBS_PRELOAD = 

  JAVA ................ = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/java

  JAVADOC ............. = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/javadoc

  JAR ................. = /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin/jar

  ANT ................. = /usr/local/bin/ant

but the issue remained the same

 thanks.

Hello,

I think that you may have more than one JDK installed on your computer. The problem

with error: package javax.annotation does not exist

is likely due to  java 11. Make sure that at configure time the right JDK is detected, and if necessary force the detection with  configure flag

--with-jdk=DIR

and/or

export JAVA_HOME=`/usr/libexec/java_home -v '1.8*'`

Hi,

I still can’t find any Scilab 6.1 builds for macOS (despite the info text here: https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/www.scilab.org) , so I’m trying to compile one myself.

Great, at least we will be two now...

However, I get a bunch of Java errors during compilation.

Which kind ?

I’m currently using a JDK from AdoptOpenJDK (Java 8). Is this correct,

Yes.

S.

or should I try using some other version or provider for compiling Scilab on macOS Catalina?

Cheers,

Arvid
