Hi,


Probably, but I won't count too much on 32 bits binary because we tried = two RPM emacs packages, one from IBM website and the other from BULLFREEWAR= E website and they both ended with a "Segmentation Fault" with a = core dump when we execute "emacs".


I also played with LDR_CNTRL variable without any success.<= br>


It seems that AIX 7.1 is very memory strict with 32 bits binaries and I'= m sure that "unexec" is doing some memory dump to the final emacs= binary that AIX 7.1 doesn't like.


That's why I'm tyring to compile in 64 bits.


For the moment, "temacs" in 64 bits works well but slow to sta= rt.  I'm stuck at 'unexaix' operation and I'm not an expert in XCOFF b= inary file.  I know that 'unexaix.c' isn't adapted for 64 bits binarie= s and I tried to make some modifications as I wrote earlier by enabling __XCOFF64__ in "unexa= ix.c" source code, without success since it generates a huge 4GB emacs= binary, but I know I'm not so far to fix it.


Thank you


Eric

I guess there's a deeper problem with the 64-bit build on AIX.

This sounds like some system configuration problem?  Are you sure the<= br> dynamic linker is picking up the same Glib library whose header files
the compiler saw?  Do you have another Glib shared libraries installed=
somewhere?
