Hello,

I am trying to get GNAT running since 3 days! :-( Here is my actual problem:

alpine:~/HelloAda$ gnatmake hello.adb 
gcc-4.6 -c hello.adb
gnatbind -x hello.ali
gnatlink hello.ali
/opt/gnat-debian/usr/bin/ld: warning: libc.so.6, needed by /opt/gnat-debian/usr/bin/../lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libgnat-4.6.so, may conflict with libc.so.0.9.32
 
alpine:~/HelloAda$ ./hello
Segmentation fault
 
alpine:~/HelloAda$ gnatclean hello
"./hello.ali" has been deleted
"./hello.o" has been deleted
"hello" has been deleted

But there no libraries linked against libc.so.0.9.32 as you can see at the bottom.

I installed following packages in /opt/gnat-debian

Could we get gnat work on alpine, please? :-)

Hi,

my next try was to compile gnat with the flag static on Debian and copy the binaries to alpine:

gnat-static2.tar.gz (165.1 MB)

This did not work out. :-( The binary gnatclean works, but not gnatmake for some (unknown) reason.

Okay, I tried to compile a Cross-Compiler. It's working for C, but not for Ada.

x86_64-alpine-linux-uclibc-gcc -c hello.adb

adaint.c => http://nopaste.info/ffcb612692.html

At line 3797 and 3807 in file adaint.c, I found following comment:

/* glibc versions earlier than 2.7 do not define the routines to handle
   dynamically allocated CPU sets. For these targets, we use the static
   versions. */

EDIT: I will check http://comments.gmane.org/gmane.comp.lib.uclibc.general/22736
