Singular

Hello,

I had a small trouble while compiling Singular-3-0-2 with g++ 4.0.3:

gcc -O3 -w -fomit-frame-pointer -fPIC -I./h -I. -I/usr/local/Singular/ix86-Linux/include -DHAVE_CONFIG_H -c MP_Link.c
MP_Link.c: In function ‘MP_EndMsgReset’:
MP_Link.c:493: error: invalid lvalue in assignment
MP_Link.c:494: error: syntax error before ‘}’ token
MP_Link.c: In function ‘MP_InitMsg’:
MP_Link.c:965: error: invalid lvalue in assignment
MP_Link.c: In function ‘MP_SkipMsg’:
MP_Link.c:1011: error: invalid lvalue in assignment
make[1]: *** [MP_Link.o] Error 1

I solved it by changing line 988 of the file MP/MP.h:

Old code:

#define MP_ClearError(link) ((MP_Status_t) (link)->MP_errno = MP_Success)

Correction:

#define MP_ClearError(link) ((MP_Status_t) ((link)->MP_errno = MP_Success))

After that, the software compiled just fine,
and appears to run correctly.
