Hi, small update on GCC 4.4 compilation, I managed to walk around ICE in snapshot and compile up to place where Singular fails because of use of strchr in 2 places, i.e. it uses "char * strchr(const char*, int)" while from version 4.4 gcc allows only "const char* strchr(const char*, int)" or "char* strchr(char*, int)" as described in http://gcc.gnu.org/gcc-4.4/porting_to.html and stops with:
error: invalid conversion from "const char*" to "char*" I wonder how it is that it works on any gcc 4.4 platform with above - anyway will try to build it tomorrow again and probably open ticked with some patches that were required, or attach to some current ticked depending what it will be... cheers, Andrzej.
