I have just tried to compile the Windows unit (that exports thousands of winapi routines, interfacing to the Mingw winapi libraries), and two of those routines are now rejected with the "attributes in forward declared routines are not allowed" error. There is no reason for those two routines to be singled out, and there is no USES problem here. Best regards, The Chief -------- Prof. Abimbola A.

Build problem 20030507 on 2.3.1
by Mirsad Todorovac 09 May '03

Hi, all! When I do gzip -cd <tbz2> | tar xvf -; cd ../p gcc-3.2.1; cd builddir; /home/.../gcc-3.2.1/configure --enable-languages=pascal w or w/o --prefix=/usr/local/gpc/20030507-3.2.1/ then make It didn't say that it wants to apply patch, and it also didn't build gpc in corresponding bin. I can't think of anything smart, I've done rm -rf gcc-3.2.1; gzip -cd ...; gzip -cd ...; mv .../p ...; ... several times, and I couldn't get to the point where it asked for >RETURN> before applying the patch, neither it said it did. Any idea? Architecture is i686, linux Debian woody, make is GNU make 3.80, ...

gcc 3.2.3 successes
by Prof A Olowofoyeku (The African Chief) 05 May '03

05 May '03

Hi folks I have built gpc 20030323 with gcc-3.2.3 sources, both under Cygwin and Mingw. I used the gcc-3.2.2.diff. There were no problems with either configuring or building. I have not yet run the testsuites, but everything seems okay with my own programs. Best regards, The Chief -------- Prof. Abimbola A.

`Return'
by Frank Heckenbach 01 May '03

01 May '03

`Return' currently needs special syntactic handling, only because it's (optional) argument doesn't have to be enclosed in parentheses (like in C), such as `Return 42'. The only Pascal dialect (AFAIK) that also supports `Return' is Mac Pascal. Does it work without parentheses there? If not, I suggest to change it in GPC, even if it means a few (trivial) changes in existing code.
