compiling gcc-3.4.4
by Paul Isaacs 20 Mar '16

20 Mar '16

Hello, For what its worth: To overcome an error compiling unwind-dw2, Instances of "struct siginfo" have to be changed to "siginfo_t" in gcc-3.4.4/gcc/config/i386/linux.h Regards, Paul Isaacs

more gpc bootstrapping errors
by Treutwein Bernhard 18 Mar '16

thanks for the feedback until now. I reverted back to texinfo 4.13 from the TinyCore 4.x repostitory I completely removed my working directory and started from the scratch. Now the info files are generated, but I'm still getting errors, this time the errors are more obscure to me. In file included from ../gcc-3.4.6/gcc/gcov-io.h:240, from ../gcc-3.4.6/gcc/libgcov.c:51: ./auto-host.h:188:1: warning: "HAVE_DECL_GETOPT" redefined In file included from ../gcc-3.4.6/gcc/libgcov.c:37: ../gcc-3.4.6/gcc/tsystem.h:40:1: warning: this is the location of the previous definition rm -rf ./libgcov.a ar rc ./libgcov.a libgcc/./_gcov.o libgcc/./_gcov_merge_add.o libgcc/./_gcov_merge_single.o libgcc/./_gcov_merge_delta.o ranlib ./libgcov.a /mnt/sda5/TeX-GPC/GPC/work/gcc/xgcc -B/mnt/sda5/TeX-GPC/GPC/work/gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../gcc-3.4.6/gcc -I../gcc-3.4.6/gcc/. -I../gcc-3.4.6/gcc/../include -fexceptions -c ../gcc-3.4.6/gcc/unwind-dw2.c -o libgcc/./unwind-dw2.o ../gcc-3.4.6/gcc/unwind-dw2.c: In function `uw_frame_state_for': ../gcc-3.4.6/gcc/unwind-dw2.c:1031: error: field `info' has incomplete type libgcc.mk:122: recipe for target 'libgcc/./unwind-dw2.o' failed make[2]: *** [libgcc/./unwind-dw2.o] Error 1 make[2]: Leaving directory '/mnt/sda5/TeX-GPC/GPC/work/gcc' Makefile:1228: recipe for target 'libgcc.a' failed make[1]: *** [libgcc.a] Error 2 make[1]: Leaving directory '/mnt/sda5/TeX-GPC/GPC/work/gcc' Makefile:23375: recipe for target 'all-gcc' failed make: *** [all-gcc] Error 2 Should I try to revert back also gcc? Which version would be preferred? I am currently using TinyCore 7, in version 6, there was gcc-4.9.1, version 5 had 4.7.2 and version 4 had 4.6.1. I don't really know what happens if I mix development tools from different version, but apparently most required tools are packaged in one pseudo-package. Here are the versions of the different tools I used this time: makeinfo (GNU texinfo) 4.13. gcc (GCC) 5.2.0 GNU bash, version 4.3.39(1)-release (i486-pc-linux-gnu) bzip2, a block-sorting file compressor.

gp file not found
by Paul Isaacs 15 Mar '16

15 Mar '16

Hello, I have installed gp using: make prefix=$PASCAL/local CFLAGS=-I/usr/include/i386-linux-gnu install and adding $PASCAL/local/bin to PATH gp --version reports "GP version 0.61" However gp x.pas results in "x.pas: file not found" At line 2643 in gp.pas the error message literal is "file not found". The ":" after the file name is must be from MainSrcBase If I place two source files on the command line the expected error occurs. I am using Q4OS linux and the source file is present when I do an "ls". What am I doing wrong? Thanks, Paul Isaacs

Variable length argument types for libusb binding
by Paul Isaacs 15 Mar '16

15 Mar '16

Hello, I have written a gnu pascal binding for libusb. I would like to improve it by using schemata for the various variable length libusb function arguments. I can come close by generating the USB arg pointer dynamically as follows: UsbArgPtr := UsbPtr( addr( ArraySchemata[ 1 ] ) ) to generate a pointer to the array within the schemata. This process can be hidden within the thick binding but not the thin binding. I would like to be able to declare a type that points to this address for use as an argument type in the binding functions. Is this possible? Do schemata have other attributes as well as .Size that could be used? Thanks, Paul Isaacs

Trapping RTS faults
by Paul Isaacs 14 Mar '16

14 Mar '16

Hello, The Trap unit traps system faults but does not seem to catch RTS errors ( index out of range, etc. ). Is there a way to trap RTS faults so that something like ncurses can be closed down properly? Thanks, Paul Isaacs

gpc bootstrapping fails on makeinfo
by Treutwein Bernhard 13 Mar '16

Hi all, when I try to bootstrap gpc, on a TinyCore 7.0 Linux with the necessary extensions installed. I downloaded the source distribution from http://alignment.hep.brandeis.edu/Software/Pascal/gpc-20070904-build.tar.gz and followed the instructions given in http://alignment.hep.brandeis.edu/Software/Pascal/Pascal.html But make aborts with the following error (after quite some time workin and some warnings) during the attempt to create the info files: [...] make[2]: Entering directory '/mnt/sda5/TeX-GPC/work/gcc-3.4.6/gcc/p/rts' make[2]: Nothing to be done for 'generated-files'. make[2]: Leaving directory '/mnt/sda5/TeX-GPC/work/gcc-3.4.6/gcc/p/rts' cd /mnt/sda5/TeX-GPC/work/gcc-3.4.6/gcc/p/rts && make -f Makefile.in srcdir=.
