Compiling ddd-3.3.1-r3 with gcc version 3.3.1 20030904 (Gentoo Linux 3.3.1-r1, propolice) fails, because strstream.h is missing. I found, that /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.1/include/g++-v3/backward/strstream should get a .h on the end. Another issue with this build is, that ddd uses ostrstream and istrstream without std::. I fixed this with two lines sed and editing three headers. cd /var/tmp/portage/ddd-3.3.1-r3/work/ddd-3.3.1/ find . -name *.C -exec sed -i -e 's/ostrstream/std\:\:ostrstream/g' {} \; find . -name *.C -exec sed -i -e 's/istrstream/std\:\:istrstream/g' {} \; then change in ddd/strclass.h (543, 555, 1049, 1083), ddd/Agent.h (417)and ddd/GraphNodeI.h (124) 'ostrstream' to 'std::ostrstream'. After that the build succeeds. As far as I tested till now, it works also.

Another solution is to bump version to 3.3.7 which compiles fine with gcc-3.3.1. Markus
Created attachment 17738 [details, diff] ddd.diff .diff: ddd-3.3.1-r3.ebuild -> ddd-3.3.7.ebuild
3.3.7 doesn't compile on gcc 2.9x
The GNU Webpage on DDD states the following: # DDD 3.3.7 is now available.. DDD 3.3.7 brings debugging of bash scripts (together with bashdb) and improved conformity with ISO C++: in particular, G++-3.x is now the compiler recommended for DDD. They probably should have said gcc-3.x is the "required" compiler instead of the "recommended" compiler, but it seems they are pushing for gcc-3.x acceptance. I'll create an ebuild for ddd-3.3.7 shortly to resolve this issue.
Resolving as FIXED. ddd-3.3.7 is in CVS now and there is a note in the Changelog that it will not compile with gcc-2.95.x compilers. If a bug ever pops up about that, mark it invalid.
