I should mention that opendx-4.4.4-r2 works fine.
Could you start with attaching config.log ? As I don't see a publicly available source link (one with the form doesn't count, due to the form), could you attach the macro it uses for that failing check too ?
Created attachment 193286 [details] config.log.gz
Here is the macro it uses for the failing test: dnl dnl Determine whether the stdc++ libraries are needed to compile successfully. dnl ------------------------------------------------------------- AC_DEFUN(DX_NEEDS_STDCXX, [ AC_MSG_CHECKING(whether -lstdc++ is needed) tmpLIBS=$LIBS AC_CACHE_VAL(ac_cv_requires_lstdcxx, [ AC_LANG_PUSH([C++]) AC_LINK_IFELSE([AC_LANG_PROGRAM([[ #include <iostream.h> ]], [[ cout << "foo"; ]])],[ac_cv_requires_lstdcxx="no"],[ LIBS="$LIBS -lstdc++" AC_LINK_IFELSE([AC_LANG_PROGRAM([[ #include <iostream.h> ]], [[ cout << "foo"; ]])], [ac_cv_requires_lstdcxx="yes"], [ AC_MSG_RESULT(failed even with lstdc++) exit 1 ] ) ]) AC_LANG_POP([]) ]) AC_MSG_RESULT(${ac_cv_requires_lstdcxx}) ])
The interessting part of the config.log is: configure:39260: x86_64-pc-linux-gnu-g++ -o conftest -march=core2 -pipe -fno-strength-reduce -Wl,-O1 conftest.cpp -lnsl -lXpm -ltiff -ldl -lXm -lXp -lGLU -lGL -lm -lXext -lXt -lX11 -lSM -lICE -lpthread -lstdc++ >&5 conftest.cpp:262:25: error: iostream.h: No such file or directory conftest.cpp: In function 'int main()': conftest.cpp:268: error: 'cout' was not declared in this scope
I don't have iostream.h installed (whell I have the one from the boost libraries but it's not what this program is looking for): it is possible that this bug is related with the gcc-4.3?

I see that there is an gcc-4.3 patch for opendx-4.3. If it's just a matter of backporting it and fixing the autoconf macros than I think that I should be able to handle it and do it in a week or so (I am supposed to be working on my thesis right now :D). If it turns out that opendx needs a big patch with the possibility of me breaking something while doing it than I will report it here and leave it to someone else...
Created attachment 193304 [details, diff] opendx-4.3.2-gcc43.patch It took me less then what I fought: I just "ported" (I just applied it) the opendx-4.4.4-gcc43.patch and fixed that test in the acinclude.ac. With this patch opendx now builds fine here and it *seems* to work: I just tried a couple of examples and as I have no previous experience with opendx (was actually trying it for the first time when I hit this bug) and as there seems not to be any testsuite I cannot be sure that everything is ok: the patch by itself is inoffensive, but there could be some other nasty gcc-4.3 related bug.
Created attachment 193374 [details] opendx-4.3.2-gcc43.patch Maybe I rushed too much with the previous patch: I have rebuilt opendx again and this time I had to do some more patching (I don't really know why it worked fine in the first place: I emerged it twice without any USE or lib change and the second time it stopped working), I also cleaned the initial patch a bit and tested it with USE=+*.

opendx-4.4.4-r2 now in main tree. thanks
