[Scilab-Dev] ilib_build with C++ and Fortran sources

[Stéphane Mottelet]

Hello Clément,

I have two kinds of behavior between 6.0.1 and branch-6.0.

Under 6.0.1, I am not even able to build toolbox_skeleton, with the same 
error message (problem when compiling fortran, again)

-- Création de [toolbox_skeletonlib] (Macros) --
genlib : Traitement du fichier : scilab_error.sci
genlib : Traitement du fichier : scilab_sum.sci

make: *** [fsum.lo] Error 1
ilib_compile : La commande était :make  CFLAGS=" -D__SCILAB_TOOLBOX__ 
-I/Applications/scilab-6.0.1.app/Contents/MacOS/share/scilab/../../include/scilab/ 
-I/Applications/scilab-6.0.1.app/Contents/MacOS/share/scilab/../../include/ 
" CXXFLAGS=" -D__SCILAB_TOOLBOX__ 
-I/Applications/scilab-6.0.1.app/Contents/MacOS/share/scilab/../../include/scilab/

" 
FFLAGS="-I/Applications/scilab-6.0.1.app/Contents/MacOS/share/scilab/../../include/scilab/ 
"

Under branch-6.0, I can build toolbox_skeleton,

The first fortan files are rapidely processed,  but when the first c or 
c++ files have to be compiled, ilib_gen_make reruns the configure script 
and it takes almost 5 minutes to complete !

5 minutes stuck here.

Do you have an idea ?

Passing all of them together imply that the compilers will handle similar command-line  arguments which is not the case in your system.  Could you send us the config.log file from the toolbox ?
