[Freedos-user] DJGPP / gcc crash
Hello, I installed recently the FreeDOS 1.1 distro on a VirtualBox machine, installed the latest DJGPP, and tried to run gcc from there... Unfortunately, all I got is this: C:\DJGPP\BINgcc Exiting due to signal SIGSEGV Page fault at eip=00041381, error=0004 eax= ebx=0016bba0 ecx=0001 edx= esi=001f22b8 edi=b078 ebp=001f2298 esp=001f20d0 program=C:\DJGPP\BIN\GCC.EXE cs: sel=00a7 base=0040 limit=001f ds: sel=00af base=0040 limit=001f es: sel=00af base=0040 limit=001f fs: sel=008f base=a380 limit= gs: sel=00bf base= limit=0010 ss: sel=00af base=0040 limit=001f App stack: [001f2394..00172394] Exceptn stack: [00171d9c..0016fe5c] Call frame traceback EIPs: 0x00041381 0x0004080a 0x0014b108 C:\DJGPP\BIN Anybody knows what this could be? Is there any known incompatibility between the DJGPP GCC and FreeDOS? I'm using the stock Jemmex manager, but tried with bare HIMEMX and XMGR with same result... regards, Mateusz -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Freedos-user] DJGPP / gcc crash
Hello Rugxulo, Thank you very much for your expert reply. I have some quite extensive experience with GCC on linux, but actually never tried to use the monster on FreeDOS. I see that DJGPP is not as much user friendly as the gcc I'm used to. set DJGPP=c:\djgpp\djgpp.env This was exactly the problem. First, I had no DJGPP environnement variable at all, then I was setting it naively to point to the directory where DJGPP is installed (C:\DJGPP\) - but only setting it to the value you gave actually solved the problem, and made GCC not crash anymore. Hooray! I'm quite surprised that GCC doesn't checks if the %DJGPP% variable is set, and makes some sense... On the other hand, I should have read the readme file, which provides the correct content for the variable at line #224... :) Thank you!
