Compiling gpc-19991030 fails on rts.c
by J. David Bryan 23 Jan '00

Dear ListFolks, I am attempting to make an i486-pc-mingwmsvc (i.e., Windows NT standalone) version of the latest gpc alpha (gpc-19991030) using the Cygwin B20.1 emulation, and I get a compilation error when the build process attempts to make the run-time library. Specifically, I get: /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c: At top level: /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:577: warning: `struct passwd' declared inside parameter list /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:577: warning: its scope is only this definition or declaration, which is probably not what you want. /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c: In function `_p_pwl2c': /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:579: dereferencing pointer to incomplete type /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:592: dereferencing pointer to incomplete type /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:593: dereferencing pointer to incomplete type /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:594: dereferencing pointer to incomplete type /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c:595: dereferencing pointer to incomplete type I don't know enough C to be sure, but this looks like a syntax error. Surely, though, it must compile on other systems, so I'm stumped. Perhaps it has something to do with the Cygwin-specific version of gcc? As far as I can tell, everything was unloaded, patched, and configured correctly. The compiler itself appears to have been made correctly, i.e., I have xgpc.exe, gpc1.exe, and gpc-cpp.exe in the object directory. The invocation on the RTL appears to be: ../../i486-pc-mingwmsvc-gcc -c -I. -W -Wall -Wpointer-arith -Wwrite-strings -Wmissing-prototypes -Wmissing-declarations -g -O2 -DRTS_RELEASE_STRING="'__GPC_RTS_VERSION_`cat /usr/local/src/gcc-2.95.2/gcc/p/rts/rts_release`__'" -DBSD_RTS=0 `if [ x@with_shared@ = xyes ] ; then echo -fPIC; fi` -v /usr/local/src/gcc-2.95.2/gcc/p/rts/rts.c I've tried compiling rts.c with gcc-2.8.1 as a test, and I get the same error. Could someone point me in the right direction? Thanks! -- Dave

But lately I just install GNU autoconf to get rid of the trouble. Usually, you should not need autoconf if you just want to install GPC (or most other packages as well). autoconf is used by the developers to create the configure scripts which are invoked during building GPC. You should only need autoconf if you've changed the configure.in file or something like that... > -- B) error messages start here -- > ../.././xgpc -B../.././ -c -I. -W -Wall -Wpointer-arith -Wwrite-strings > -Wmissing-prototypes -Wmissing-declarations -O2 -g -O2 > -DRTS_RELEASE_STRING="'__GPC_RTS_VERSION_`cat > /opt/OV/tmp/gcc-2.95.2/gcc/p/rts/rts_release`__'" -DBSD_RTS=0 `if [ > x@with_shared@ = xyes ] ; then echo -fPIC; fi` > --unit-path=/opt/OV/tmp/gcc-2.95.2/gcc/p/rts --automake > /opt/OV/tmp/gcc-2.95.2/gcc/p/rts/files.pas > /opt/OV/tmp/gcc-2.95.2/gcc/p/rts/string2.pas: In function `Getenv': > /opt/OV/tmp/gcc-2.95.2/gcc/p/rts/string2.pas:193: internal > error--unrecognizable insn: > (insn 15 14 17 (set (zero_extract:SI (reg:SI 97) > (const_int 32 [0x20]) > (const_int 0 [0x0])) > (reg:SI 98)) -1 (insn_list 12 (insn_list 14 (nil))) > (expr_list:REG_DEAD (reg:SI 98) > (nil))) > gpc1: ../.././xgpc exited with status 1 > /opt/OV/tmp/gcc-2.95.2/gcc/p/rts/files.pas:30: module/unit `string2' could > not be compiled > make[3]: *** [files.o] Error 1 This problem seems to be in the compilation of CString2String. Since Peter is working on the string handling, anyway, there might be some hope that it will be fixed soon.

I suppose, the (binary) GCC uses HP's linker, does it (if unsure, you can check it by watching the output of `gcc -v')? If so, GPC should be able to do the same (and as far as I understood the problems, so far they only concerned the assembler, not the linker, anyway).

The best I can tell you right now is to wait for the next snapshot, and then use it together with `os-hacks.h'. Though using `os-hacks.h' with the last alpha should yield some improvements already, it will not solve all problems and probably cause you additional debugging effort for problems that have been solved recently, like the one above...

None
by Ivan Torshin 21 Jan '00

Hello, I'm trying to compile GPC under linux using unix sources. (in order to compile pascal programs written for BP 7.0 but it is another story). The GCC 2.95 and GPC were downloaded and dealt with as it is described in the GPC/p/INSTALL file. Howevre, there are no diff file gcc-2.95.diff and mkdiff script also seems to be of little use (for making this file). running make LANGUAGES=pascal in the outer (gcc) directory does not lead to gpc executable, of course. Could someone help me with it? I'm a novice in compiling compilers, as usually all DOS/Windows programs are ready made, although may contains viruses. Thank you, Ivan.

GRAPH
by Nash Jamie 21 Jan '00

21 Jan '00

This is my first message to this list, hello to you all...... I'm an Ex-TP programmer, but now 99% of my code is written in DELPHI. I was wondering if there is an equivilent to the old GRAPH unit with TP for gpc? If so what is it? Do I have it? (I thought I downloaded everything) And if I don't have it, could someone send it to me??????? (If it exists obviously......) Preferably binary (Linux) or source to the above address Thanks alot.....

build failure on Alpha

But the most recent version that we got to work here is an alpha version date 19980901 together with egcs-1.1. The newer alpha versions fail to compile. I mailed this to the gpc-list November 3 1999, but regrettably the archive does not contain messages after Oktober 1999. But anyway the gas problem (and solution) is described in the gcc documentation. The ad hoc solution that I have been using several years is the following. First: you need gas. Before making gcc/gpc: put a symbolic link such as "ln -s /usr/local/bin/gas as" in the gcc-build directory. The make process will use this "as". After installing: e.g. in /opt/gcc, add the same symbolic link in the directory where the main compiler code resides, e.g. in /opt/egcs/lib/gcc-lib/hppa1.1-hp-hpux10.20/egcs-2.91.57/ (in our case) The gcc/gpc version will use this "as". This kludge has always worked for me. But again current gpc will fail to compile:(. Sietse

Perhaps you might want to ask the GCC list <gcc(a)gcc.gnu.org> how they get GCC running on HP/UX. They might also have the required binaries (except GPC). I've never used HP/UX so I don't know exactly what you need. Is there someone on this list using HP/UX?

Thanks Frank, I used to use Solaris and seldom worked on HP myself. I did get gcc binary package from HP's web site. Although I was surprised to learn gnu ld won't compile on HP. Doing web search find me nothing on gpc associated with HP. I would appreciated if anyone has links to gpc / gnu-ld on HP. It seemed to me that I still have lot of things to learn especially on HP.
