The version of GCC shipped with Red Hat 4.2 (2.7.0.2) has a fault wherein it will silently generate incorrect code. The version shipped with Red Hat 5.0 (2.8.0.1) is not broken, but required an extra -m21164a argument on the command-line. In order to visibly trap 2.7.0.2, I now issue DEC's .arch pseudo into the assembly. Relieving the problem of mucking with command-line arguments for 2.8.0.1 is a pleasant side effect. If you've got Red Hat 5.0 installed, you may grab binutils 2.9.1 and be happy. If you've got Red Hat 4.2, bugs make it much harder to upgrade pieces on your own, and you are better off upgrading the entire system. In either case, your problem may be bypassed by not emitting BWX code by default. Do this by using configure alphaev5-unknown-linux-gnulibc1 if you have RH 4.2, or configure alphaev5-unknown-linux-gnu if you have RH 5.0. The following error: Error: macro requires $at register while noat in effect also indicates that you should upgrade to a newer version of the assembler, 2.9 or later. If you can not upgrade the assembler, the compiler option "-Wa,-m21164a" may work around this problem.

sockets, clients and servers
by Horst Herb 16 Feb '00

16 Feb '00

I am new to GPC, never used it before, just downloaded it. Pascal is my "old love", and I would like to use it again. I would like to use GPC instead of C++ for a new project. It is a client-server application, where clients communicate via TCP with the server. How can I access the sockets library from GPC? Any wrapper libraries yet? Any suggestions,especially examples, welcome. Horst

gpc on a DEC Alpha
by Olivier Lecarme 14 Feb '00

I tried to install gpc 19991030 on top of gcc-2.95.2, on a DEC Alpha computer with OSF 4.0e. According to suggestions made by Nicola Girardi, I proceeded in the following way : tar xvfz gcc-2.95.2.tar.gz tar xvfz gpc-19991030.tar.gz mv gpc/p gcc-2.95.2/gcc/ cd gcc-2.95.2 mkdir gpc ../configure --enable-languages=pascal [ here the necessary patch was applied ] make The last step terminates with the following results : ../.././xgpc -B../.././ -c -I. -W -Wall -Wpointer-arith -Wwrite-strings -Wmissing-prototypes -Wmissing-declarations -g -O2 -DRTS_RELEASE_STRING="'__GPC_RTS_VERSION_`cat /net2/ciceron2/ol/src/Install/gcc-2.95.2/gcc/p/rts/rts_release`__'" -DBSD_RTS=0 `if [ x@with_shared@ = xyes ] ; then echo -fPIC; fi` --unit-path=/net2/ciceron2/ol/src/Install/gcc-2.95.2/gcc/p/rts --automake heap.pas error.pas: In function `Geterrormessage': error.pas:365: Internal compiler error in `copy_to_mode_reg', at explow.c:669 Please submit a full bug report.

gpc 19991030 and gcc 2.95.2
by Olivier Lecarme 13 Feb '00

13 Feb '00

I have been suggested to try building the last alpha version of gpc instead of 19990118, called the current one on the official site. I tried to build on top of gcc-2.95.2 on a DEC Alpha computer. "configure" runs without any warning, and without requiring any to aply any patch. "make LANGUAGES=pascal" terminates prematurely with the following error message : make[1]: *** No rule to make target `pascal', needed by `native'. Stop. make[1]: Leaving directory `/net2/ciceron2/ol/src/Install/gcc-2.95.2/gcc' make: *** [all-gcc] Error 2 Am I missing something ? -- Olivier Lecarme

GPC on DEC Unix (OSF)
by Olivier Lecarme 13 Feb '00

13 Feb '00

I just installed gpc on a DEC Alpha computer with DEC Unix (OSF) version 4.0e. The installation with gcc 2.8.1 ran without error, and gpc answers as follows : zenon(~)31: gpc -v Reading specs from /usr/local/lib/gcc-lib/alphaev56-dec-osf4.0e/2.8.1/specs gpc version 19990118, based on gcc-2.8.1 Program compiling runs correctly. However, when trying to execute any generated load image, the error message is always the same : internal error: duplicate constructor Is there any explanation? Did I get the correct versions of gpc and gcc? -- Olivier Lecarme

current gpc vs. current gcc
by Olivier Lecarme 13 Feb '00

13 Feb '00

I just successfully installed the last gpc, using the gcc-2.8.1 distribution. However, the current gcc distribution is 2.95.2, which was previously installed on the same machine. Thus, I would like to ask: - whether gpc can be installed using gcc-2.95.something (it seemed to me that it didn't work); - or whether gpc-2.8.1 can coexist with gcc-2.95.2 on the same machine. Thanks in advance, -- Olivier Lecarme

Did I get the correct versions of gpc and gcc? That's a known bug with that version. It's fixed in later alpha versions. You can simply remove or uncomment the misleading warning in rts/misc.c and rebuild. It's harmless.
