Hello!

I try use glpk for c#. 

I’m widows 10 and VS 2015 amd 64-bit Windows. But my application is 32
bit.

I add libglpk-cli.dll to project and add libglpk_cli_native and
glpk_4_60 to /bin directory.

Test to solve was excellent.

When I try use glpk in me application 

 

InGLPK.glp_add_cols(lp, varcounter), when varcounter= big number, for
example varcounter=4961

I get exception

'GLPK.glp_add_cols(lp, varcounter)' threw an exception of type
'System.AccessViolationException'

   Data: {System.Collections.ListDictionaryInternal}

   HResult: -2147467261

   HelpLink: null

   InnerException: null

   Message: "Attempted to read or write protected memory. This is often
an indication that other memory is corrupt."

   Source: "libglpk-cli"

   StackTrace: "  at org.gnu.glpk.GLPKPINVOKE.glp_add_cols(HandleRef
jarg1, Int32 jarg2)\r\n  at org.gnu.glpk.GLPK.glp_add_cols(glp_prob P,
Int32 ncs)"
