Hi! Nothing is certain in this world :) The problem is most likely that the arm build daemons are slow and have little RAM: 128MB I think, whereas the source files in ginac use, well, I saw one file using 133MB VRAM with 128MB RSS to compile; I guess that one file needs just enough more to make them thrash. You should contact the arm buildd admin to ask for ginac to be scheduled on the machine with the most RAM, and for the inactivity timeout for it to be increased. I just compiled ginac for arm on a 600MHz box with 512MB, and it ran to completion in For the function in question, the .lo compilation took 137MB of virtual memory and 17 minutes, and the final one (that died before) took 133 MB VM and 18 minutes. I limited them to 120MB resident physical RAM, and they were fine - I guess the netwinder only has 64MB, not quite enough to cope. I noticed a "characters are signed" bug in the first source file, add.cpp, filed as bug #479163 with patches to fix it. I don't know why it wasn't flagged in the build log you indicate. The other "comparison between signed and unsigned integer expressions" warnings that I've checked are harmless, due to if (int i=0; i<limit; i++) constructs that should be if (unsigned i=0; i<limit; i++) or if (size_t i=0; i<limit; i++) according to the type of the unsigned limit variable or function. It would be good to check and fix them all upstream so that the warnings that highlight real problems will stand out. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
