If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc. You're using which OS? Groetjes, Berend (-: fido: 2:281/527.23 email: berend(a)beard.nest.nl

GNU Binary for SGI
by Oliver Puetz 03 Jun '99

03 Jun '99

Hi, I've downloaded the binary beta "gpc-19990118_mips-sgi-irix6_2_tar.gz" from ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/beta/binary/, as I'm not really familiar with unix. It should run on a SGI, Power-Challenge-XL12 with IRIX64 v6.2. GCC v2.7 is already installed. The environmental variable GPC_EXEC_PREFIX does not seem to work, setting the dir with -B as a command option helps. By compiling a little test program (no uses etc) a fatal error occured: ld32: FATAL 9: I/O error (-lgpc): No such file or directory I've copied the files from /gpc/usr/local/lib/gcc-lib/mips-sgi-irix6.2/2.8.1 into the bin-dir, but it doesn't helped. Can anyone help or had made experiences with this version?

conformance tests

I am developing a Pascal interpreter adapted for simulation of biological systems. I want to check my interpreter, and could you please let me know how (or if) I can get conformance tests? Thank you. Hangil Chang.

Yes, that's a new bug. Since it only shows on systems without cosl() etc. in their libm, like DJGPP, we didn't note it so far. Here's the fix, if you have the GPC sources and can recompile them: diff -p -r -U3 -N -X /home/frank/script/gpcdiff.exclude orig/p/rts.c p/rts.c --- orig/p/rts.c Wed Feb 17 21:56:06 1999 +++ p/rts.c Wed Feb 24 02:01:13 1999 @@ -78,16 +78,16 @@ struct rts_symbol rts[] = { { r_COLLECT,"_p_collect", NULL_RTX, NULL_TREE, 0}, - { p_ARCTAN, "atan", NULL_RTX, NULL_TREE, 0}, - { p_COS, "cos", NULL_RTX, NULL_TREE, 0}, + { p_ARCTAN, "_p_arctan", NULL_RTX, NULL_TREE, 0}, + { p_COS, "_p_cos", NULL_RTX, NULL_TREE, 0}, { p_EXP, "_p_exp", NULL_RTX, NULL_TREE, 0}, { p_LN, "_p_ln", NULL_RTX, NULL_TREE, 0}, - { p_SIN, "sin", NULL_RTX, NULL_TREE, 0}, + { p_SIN, "_p_sin", NULL_RTX, NULL_TREE, 0}, { p_SQRT, "_p_sqrt", NULL_RTX, NULL_TREE, 0}, - { pp_ARCTAN, "atanl", NULL_RTX, NULL_TREE, 0}, - { pp_SIN, "sinl", NULL_RTX, NULL_TREE, 0}, - { pp_COS, "cosl", NULL_RTX, NULL_TREE, 0}, + { pp_ARCTAN, "_pp_arctan", NULL_RTX, NULL_TREE, 0}, + { pp_SIN, "_pp_sin", NULL_RTX, NULL_TREE, 0}, + { pp_COS, "_pp_cos", NULL_RTX, NULL_TREE, 0}, { pp_EXP, "_pp_exp", NULL_RTX, NULL_TREE, 0}, { pp_LN, "_pp_ln", NULL_RTX, NULL_TREE, 0}, { pp_SQRT, "_pp_sqrt", NULL_RTX, NULL_TREE, 0}, Otherwise, you can work around the bug until the next release by linking the following C file: #include <math.h> long double sinl (long double x) { return sin (x); } long double cosl (long double x) { return cos (x); } long double sqrtl (long double x) { return sqrt (x); } long double logl (long double x) { return log (x); } long double expl (long double x) { return exp (x); } long double atanl (long double x) { return atan (x); } long double powl (long double x, long double y) { return pow (x, y); } Frank -- Frank Heckenbach, frank(a)fjf.gnu.de http://fjf.gnu.de/ PGP and GPG keys: http://fjf.gnu.de/plan

bug in sin/cos (longreal) ?
by Maurice Lombardi 23 Feb '99

23 Feb '99

Hi all, I have found a strange bug which popped up in the last beta. when compiling the following short program program bug; var x:real; y:LongReal; begin x:=1; y:=1; writeln(cos(x)); writeln(cos(y)); writeln(cos(pi*x)); end. the linker says that it cannot find module cosl in the lines containing the second and third writeln which demand for cos(longreal) either directly or indirecly (presumably pi is long real). It popped up when I tried to recompile old programs which used a lot of cos(pi* ). With grep I do not find cosl (and sinl) in any library, only in gpc1.exe (and similars cc1.exe cc1plus.exe f771.exe). Have I missed something in the installation ? (I work with DJGPP / gpc-19990118_i386-pc-djgppv201.zip) thanks in advance ! -- Maurice Lombardi Laboratoire de Spectrometrie Physique, Universite Joseph Fourier de Grenoble, BP87 38402 Saint Martin d'Heres Cedex FRANCE Tel: +33 (0)4 76 51 47 51 Fax: +33 (0)4 76 51 45 44 mailto:Maurice.Lombardi@ujf-grenoble.fr

I think it is a good idea. I had been considering starting the effort on this myself. It should make the front end simpler. Nick.
