Hi there, Every time I try to connect to ftp.uni-kl.de with the Cygwin install as per the instructions, I get a message which says that setup.ini can't be found, and then when a package repository is listed, Singular isn't in it. I am running 64-bit Windows and I've already installed Cygwin. Thanks! |

Was able to install with 32-bit, but can't start Singular from Cygwin. |

2 remarks: - currently only the binary for 32bit cygwin exists, that means it will not work in a 64bit cygwin environment - Singular uses the following dynamic libraries, but they all belong to the default cygwin installation (or the system): ntdll.dll => /cygdrive/c/Windows/SYSTEM32/ntdll.dll (0x77ad0000) kernel32.dll => /cygdrive/c/Windows/system32/kernel32.dll (0x761f0000) KERNELBASE.dll => /cygdrive/c/Windows/system32/KERNELBASE.dll (0x75e90000) cygwin1.dll => /usr/bin/cygwin1.dll (0x61000000) cygreadline7.dll => /usr/bin/cygreadline7.dll (0x6f880000) cygncursesw-10.dll => /usr/bin/cygncursesw-10.dll (0x6f9a0000) USER32.dll => /cygdrive/c/Windows/system32/USER32.dll (0x77720000) GDI32.dll => /cygdrive/c/Windows/system32/GDI32.dll (0x77570000) LPK.dll => /cygdrive/c/Windows/system32/LPK.dll (0x774e0000) USP10.dll => /cygdrive/c/Windows/system32/USP10.dll (0x77c80000) msvcrt.dll => /cygdrive/c/Windows/system32/msvcrt.dll (0x77430000) cyggcc_s-1.dll => /usr/bin/cyggcc_s-1.dll (0x6fd20000) cygstdc++-6.dll => /usr/bin/cygstdc++-6.dll (0x6f6e0000) cyggmp-10.dll => /usr/bin/cyggmp-10.dll (0x6fc70000) cygmpfr-4.dll => /usr/bin/cygmpfr-4.dll (0x6fa20000) IMM32.DLL => /cygdrive/c/Windows/system32/IMM32.DLL (0x76090000) MSCTF.dll => /cygdrive/c/Windows/system32/MSCTF.dll (0x77230000) I.e. make sure that you have readline, gmp, mpfr and ncurses installed. Use (and missing shared libraries) can be found with: ldd /usr/bin/Singular.exe |

- Solution for dynamic module: Singular uses dynamic modules at 2 places: * for polynomial operations but there is a variant without dynamic modules the configure options Code: --disable-p-procs-dynamic --enable-p-procs-static should select this variant (configure should automatically select this on Windows) * for optional pacakages can be embedded via Code: ----with-builtinmodules=a,b,c Technical background: dynamic modules are shared libarires with unresolved symbols from the Singular kernel. The dynamic linker on ELF systems (and on HPUX) resolves theese references automatically during the loading. AFAIK the dynamic linker on Windows cannot do this, so dynamic modules (at least currently) cannot work on Windows, but work-arounds exists - see above. |
