Hello everyone, recently I've a problem building rawstudio-svn on x86_64. Unfortunately it seems that the problem doesn't lie in the rawstudio itself, because I'm not able to build any older revision which I was able to build before. The error is: application.c: In function ‘segfault_sigaction’: application.c:599:56: error: ‘REG_RIP’ undeclared (first use in this function) application.c:599:56: note: each undeclared identifier is reported only once for each function it appears in application.c:617:44: error: ‘REG_RAX’ undeclared (first use in this function) application.c:619:30: error: ‘REG_RBX’ undeclared (first use in this function) application.c:621:30: error: ‘REG_RCX’ undeclared (first use in this function) application.c:623:30: error: ‘REG_RDX’ undeclared (first use in this function) application.c:625:30: error: ‘REG_RSI’ undeclared (first use in this function) application.c:627:30: error: ‘REG_RDI’ undeclared (first use in this function) application.c:629:30: error: ‘REG_R8’ undeclared (first use in this function) application.c:631:30: error: ‘REG_R9’ undeclared (first use in this function) application.c:633:30: error: ‘REG_R10’ undeclared (first use in this function) application.c:635:30: error: ‘REG_R11’ undeclared (first use in this function) application.c:637:30: error: ‘REG_R12’ undeclared (first use in this function) application.c:639:30: error: ‘REG_R13’ undeclared (first use in this function) application.c:641:30: error: ‘REG_R14’ undeclared (first use in this function) application.c:643:30: error: ‘REG_R15’ undeclared (first use in this function) application.c:645:30: error: ‘REG_RSP’ undeclared (first use in this function) I did a grep on /usr/include and /usr/lib but nothing defines any of these. My guess is that the problem may be caused by a new gcc. I should note I already searched on google but without any success (most results were saying that instead of REG_EIP, REG_EAX and others the REG_RIP etc. should be used on 64bit systems). What do you think where is the source of the problem? Regards, Lukas
