Hello,
I have problem installing and running gnat-3.11p on my Linux box.
Here is the config:
Redhat 6.0 (glibc 2.1 + egcs-1.1.2)
gcc-2.8.1
gnat-3.11p
The problem is that since I don't have the egcs source tree,
I download the gcc-2.8.1 tar ball. I've also use gnat-3.11p binary
pre-build for glibc (the ftp site didn't specify which version
of glibc it built on) as the previous version of GNAT.
I then extract all the tar balls, do a simple installation of the
binary dist of gnat-3.11p, and point the gcc to that one instead
of my original one (egcs). I followed the instruction from the
gnat-3.11p-src and did the following:
cd gcc-2.8.1
patch -p0 < ../gnat-3.11p-src/src/gcc-*.dif
mv ../gnat-3.11p-src/src/ada .
cd ada
touch treeprs.ads a-[es]info.h nmake.ad[bs]
cd ..
./configure --enable-thread --with-elf --prefix=/opt/gnat
make CC=gcc CFLAGS="-O2" LANGUAGES="ada"
make CC=gcc CFLAGS="-O2" LANGUAGES="ada" bootstrap
make CC=gcc CFLAGS="-O2" gnattools
make CC=gcc CFLAGS="-O2" GNATLIBCFLAGS="-O2" gnatlib ---------(1)
make install LANGUAGES="ada"
Actually the build is fine, and I know that this build will use native
thread instead of fsu one. The problem is that when I run the example
program diners (hello and other do really work), the prompt seems to
me that it is not responding... Doing a strace on this I found that
the program is causing a seg fault...

I then try the build with fsu:
make CC=gcc CFLAGS="-O2" GNATLIBCFLAGS="-O2" THREAD_KIND=fsu gnatlib
and diners works. However, when I tried to build glade, I learnt from
the README that on Linux, the GNAT has to be compiled in native thread.
Have anyone experience this installation config before? Please help.
Thanks in advance!
Regards,
Kit
