--- Comment #2 from Georg Bauhaus <bauhaus at futureapps dot de> 2011-04-15 14:16:38 UTC --- I did first run $ make boostrap which I should have stated less implicitly, sorry. And then, as the report says, $ make check # with -k, actually. ACATS results were good and only then # make install (I also noticed that I'm not the first to run into the issue, according to Google search results for gnatmake error: gnatmake: "xgnatugn.ali" incompatible ALI file, please recompile. First thing that turns up is msg26991 on the GCC help list.) The part with the incorrect ALI file was easily reproduced in isolation: - After the failed install, the output of $(which gnatmake) was /usr/local/bin/gnatmake - There was no /usr/local/bin/gcc yet (because the install had stopped at the above issue). - I changed dicteory to the one with xgnatugn.* in it. Removed the ALI file and ran $ gnatmake xgnatugn # this would be the new /usr/local/bin/gnatmake to get gnatmake: "xgnatugn.ali" incompatible ALI file, please recompile gnatmake: "xgnatugn.adb" compilation error This is one reason why I was guessing that gnatmake would invoke /usr/bin/gcc, not any of the newly created gccs, because these had not yet been installed successfully. The new gnatmake would invoke the gcc that is finds in the path, which is not among any of the new gccs. I have started again using a absolute path to configure, as you have suggested. After removing everything from the /usr/local hierarchy, and $ hash -r. $ ls -l /opt/src/MAINTAINERS -rw-r--r-- 1 bauhaus bauhaus 21058 Apr 11 19:52 /opt/src/MAINTAINERS $ pwd /opt/build $ ls -a . .. $ which gcc /usr/bin/gcc $ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games $ gcc -v # compiler to be used for make bootstrap Using built-in specs.
