GCC 3.4.4-2 libg2c vs. lib search path

2006-12-04 Thread Axel Naumann
Hi, yes, I have gcc-g77 installed :-) GCC 3.4.4-2 can't find libg2c.a; look e.g. at gcc -lg2c vs. gcc -lm. The same problem exists for libfrtbegin.a. This looks like a regression from 3.4.4-1. The cygwin package search tells me: 3.4.4-1: usr/lib/gcc/i686-pc-cygwin/3.4.4/libg2c.a 3.4.4-2: usr/lib

new vs malloc, -fno-exception - Re: Serious performance problems (malloc related?)

2005-06-02 Thread Axel Naumann
Hi, here's a little study, allocating / freeing mem in a loop, once with the C malloc/free, once (-DUSE_CXX_HEAP) using new/delete. It reproduces the factor ~3 for gcc cygwin. I've built it with MSVC's cl 7.0, gcc 3.3.3, with and without -mno-cygwin, using the cygwin-inst snapshot from 20050528,

vtable with snapshot >=20031123

2003-12-12 Thread Axel Naumann
Hi, I ran into a problem with gcc 3.3.1, cygwin snapshots>=20031123 (at least, probably also earlier versions). The binary built from the attached sources (with vtbllib.hpp's INLINE_CTOR defined) coredumps. It seems that the vtable is invalid, probably because a class's vtable is created for e

cyg 1.5.5-1: fgetpos returns -1 problem

2003-10-27 Thread Axel Naumann
Hi, I have a problem with glibc's fgetpos on current cygwin. Looking around I couldn't find a previous posting on it. Running this test program: --- #include int main(int argc,char**argv) { FILE *file = fopen("fo.C","rb"); // use any existing file here FILE *write= tmpfile(); char c =
