The game "dungeon" fails to build from source. "emerge dungeon" yields this error: f2c -A -C -Nn802 -NL400 rooms.f Compiler error line 740 of objects.f: start_formatting: couldn't open the intermediate file I/O error on pass1_file make: *** [objects.c] Error 3 Attempting "strace -f -o dungeon.log emerge dungeon" as root yielded either that error at a different file and line, or segmentation faults. Without strace, the emerge always fails at the same place. Based on what I can get from the strace logs on this heisenbug, it looks like it's failing because an open of a file named p1_file fails with ENOENT. This is in spite of the fact that a subsequent unlink succeeds.
Created attachment 51581 [details] Fixed ebuild error. Changed from emake -> make fixed problem.
Tried it by editing the dungeon-3.2.3.ebuild directly, that got it to emerge correctly. Thank you.
Bah. Fixed it to build in parallel. f2c seems to step on itself. Thanks for the bug report.
