Bug in EiffelStudio build scripts?

[Greg Lee]

Hi.

I recently downloaded and attempted to build the EiffelStudio source from svn. I used the geant automated build scripts. I am running LInux Mint 17 (64 bit) on VirtualBox running on Windows 7 with a GPL install of EiffelStudio 14.05 for linux-x86-64.

I encountered an error while running the "geant prepare" script. The compilation was running fine up to the point in bold:

("geant prepare" output.....)

gcc -c -I../.. -I../../run-time -I../../idrs -I../../run-time/include -DWORKBENCH -DEIF_IPC -O3 -pipe -fPIC -D_GNU_SOURCE -m64  rqst_idrs.c
/bin/rm -f libipc.a
ar rc libipc.a com.o identify.o logfile.o network.o select.o shword.o stack.o stream.o system.o transfer.o rqst_idrs.o
: libipc.a
gcc -c  -DWORKBENCH -DEIF_IPC com.c -o MTcom.o
com.c:47:24: fatal error: eif_config.h: No such file or directory
 #include "eif_config.h"
                        ^
compilation terminated.
make[4]: *** [MTcom.o] Error 1
make[4]: Leaving directory `/home/leegr3/Projects/EiffelStudio/Src/C/ipc/shared'
make[3]: *** [subdirs] Error 1

make[1]: *** [subdirs] Error 1

make: *** [all] Error 2
quick_configure terminated.


Looking at the build output, it looks like the gcc command for com.c is missing some needed include directories, since eif_config.h definitely exists in the parent directories to the file com.c . I went into the makefiles that were failing and hand-edited then to add the missing include directores. That seemed to fix the error, but later on there were additional errors with the compilation of scoop.c. It looks like the gcc command for scoop.c was missing the -DEIFFEL_THREADS and -DLINUX_THREADS symbols. That hand-edited fix did not solve the problem, though. I encountered the same errors when I followed the "recommended approach" while running quick_configure.

On the web page "https://dev.eiffel.com/Compiling_EiffelStudio", you ask for errors to be reported. I believe I have followed the build instructions correctly, and that there is an error in the build scripts.

Thanks,

Greg Lee

Dear Lee,

It is not possible to compile EiffelStudio with gcc (see the note of the first section on https://dev.eiffel.com/Compiling_EiffelStudio )

You have to use Microsoft C Compiler, mainly for COM and dotnet related component.

I hope this helps,

Hi Jocelyn and Greg,

I have encountered the same behaviour like Greg. I can not agree with Jocelyn, build on Linux should use gcc (clang) there is no MS compiler.
It looks like missing CFLAGS on command line for all files in C/run-time directory

Hi,

Sorry I read too quickly the original message, I though this was on Windows, ... my mistake.

Of course, compiling EiffelStudio on Linux is using "gcc"

I will try to reproduce, and provide a better answer.

But I suspect that subversion is not properly configured , follow instruction from https://dev.eiffel.com/Subversion_Settings

and especially the "use-commit-times"="yes"

Hi,

I tried on ubuntu 14.04 64bits, and this is working fine.

My svn is configured to "use-commit-times=yes" ... which is important for the run-time compilation (make dependencies on file timestamp).

I installed EiffelStudio 14.05

And environement variables ISE_EIFFEL, ISE_LIBRARY, ISE_PLATFORM, EIFFEL_SRC are set to expected values.

With those settings the "geant prepare" works fine.

Now, Greg, if you still has issue, please let us know,

Hi,

many thanks for your advice, my fault I skip the subversion setting part. Now it compiles with gcc and with clang too. Clang has much better diagnostic than gcc and produces more warnings.

Thanks for your first message to report my bad answer, 

and thanks for the confirmation that it is also working for you.

Note that the source code has also a git mirror at https://github.com/EiffelSoftware/EiffelStudio

In the case, you want to contribute and send patch, you can do that either with subversion, or also for the git repository.

Regards,
