This file ("ftp.math.rwth-aachen.de:/pub/gap/README.problems") describes possible solutions to various problems which might occur while installing GAP 3.4 Patchlevel 1. Please send any further questions to "Gap-Trouble@Math.RWTH-Aachen.DE". Table of Contents ----------------- *Problem 1: ibm pc, ms-dos, share libraries Problem 2: dec alpha, osf1, gap Problem 3: dec alpha, osf1, xgap *Problem 4: any unix, anu sq Problem 1: ibm pc, ms-dos, share libraries ------------------------------------------ 'RequirePackage' reports "Error, share library is not installed" but I have installed the corresponding share library in "gap3r4p0/pkg". Solution This problem is fixed in Patchlevel 1. Problem 2: dec alpha, osf1, gap ------------------------------- My compiled version of GAP does not run correctly on a DEC Alpha. Solution The version of GASMAN, the GAP storage mananger, used for GAP 3.4 is not 64bit safe. In order to use GAP on a DEC Alpha you have to translate a DEC Ultrix executable using mx. A translated executable can be found in "ftp.math.rwth-aachen.de:/pub/gap/bin/bin3r4p0-dec-alpha-osf1.zoo". Problem 3: dec alpha, osf1, xgap -------------------------------- I cannot compile XGAP on a DEC Alpha because make reports "Don't know how to make xcmds.c. Stop." but "xcmds.c" is there. I cannot compile XGAP because there is no target for DEC Alpha in the makefile. Solution The first problem is due to a bug in "unzoo". Either touch all files after extracting them or use gnumake. The following command will compile XGAP make xgap CC=cc CFLAGS="-I/usr/include -O -DSYS_HAS_UNISTD \ -DSYS_HAS_STDARG" LDFLAGS=" -L/usr/lib" Alternatively you can get XGAP from our ftp server. An executable can be found in "ftp.math.rwth-aachen.de:/pub/gap/bin/xgap1r2-dec-alpha-osf1.zoo". Problem 4: any unix, anu sq --------------------------- I can compile the ANU Sq but the linker complains about a missing '_RunTime'. Solution This problem is fixed in Patchlevel 1.
