From what I see in that file, proc g++_init sets the compiler via GXX_UNDER_TEST, proc g++_target_compile uses GXX_UNDER_TEST to invoke the compiler, and proc g++_version can be used to print and therefore verify the compiler version. > In addition to that code, check out *.exp, and ../.*/*.exp and then > dejagnu/lib/*.exp and dejagnu/config/*.exp, after that, you'll be an > expert. OK. Looks like a long term project. > Wild ass guess, did you type make -k check? Yes. Is there something wrong with that? In output of make -k check, I did notice that autogen is missing, causing an "Error 2", but the test carries on regardless. Is this OK? make[1]: Entering directory `/home/leopardi/src/gcc/gcc-4.0.1-obj/fixincludes' autogen -T ../../gcc-4.0.1/fixincludes/check.tpl ../../gcc-4.0.1/fixincludes/inclhack.def make[1]: autogen: Command not found make[1]: *** [check] Error 127 make[1]: Leaving directory `/home/leopardi/src/gcc/gcc-4.0.1-obj/fixincludes' make: *** [check-fixincludes] Error 2 make[1]: Entering directory `/home/leopardi/src/gcc/gcc-4.0.1-obj/gcc' Making a new config file... SUSE packaged autogen for SUSE Linux 9.3, but not for my version, SUSE Linux 9.2. Should I just stop now, install autogen and try again? http://www.novell.com/products/linuxpackages/professional/autogen.html http://rpm.pbone.net/index.php3/stat/4/idpl/1805805/com/autogen-5.6.5-3.i586.rpm.html Also, gcc summary says: === gcc Summary === # of expected passes 34550 # of unexpected successes 1 # of expected failures 105 # of untested testcases 28 # of unsupported tests 433 /home/leopardi/src/gcc/gcc-4.0.1-obj/gcc/xgcc version 4.0.1 I guess that the last line of gcc summary is printed by proc default_gcc_version in gcc.exp.

I noticed that proc g++_init contains the code: if ![info exists GXX_UNDER_TEST] then { if [info exists TOOL_EXECUTABLE] { set GXX_UNDER_TEST $TOOL_EXECUTABLE; Does "runtest --tool g++" set TOOL_EXECUTABLE to "g++" ? Finally, in the output of "make -k check", g++ summary says: === g++ Summary === # of expected passes 9113 # of unexpected failures 2166 # of unexpected successes 16 # of expected failures 54 # of unresolved testcases 61 # of untested testcases 54 # of unsupported tests 90 /usr/bin/g++ version 3.3.4 (pre 3.3.5 20040809) I guess that the last line of g++ summary is printed by proc g++_version in g++.exp. Does this imply that proc g++_init has set the compiler via GXX_UNDER_TEST to either "/usr/bin/g++" or more likely, "g++" ?
