Problems installing...help!

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.

I have exactly the same problem. Some one can help us, please.

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

I and Yue are working on the updated cygwin package for 32 and 64 bit version
https://cygwin.com/ml/cygwin-apps/2015-04/msg00035.html

We should upload in 1-2 weeks.

- 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
should select this variant (configure should automatically select this on Windows)
* for optional pacakages
can be embedded via
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.
