Struggling to create exe with script that requires gsl

[Ruggiero Guida]

Ruby 2.7.1

I keep receiving the error when I execute ocra to convert a script that requires gsl. I have tried all the suggestions from the various comments to previous issues, but I keep receiving the error

Traceback (most recent call last):

My latest attempt at the command is

ridk exec ocra --verbose ground.rb --gem-full --dll "ruby_builtin_dlls\libgsl-25.dll" --dll "ruby_builtin_dlls\libgslcblas-0.dll" --dll ruby_builtin_dlls\libssp-0.dll --dll ruby_builtin_dlls\libgmp-10.dll --dll ruby_builtin_dlls\libgcc_s_seh-1.dll --dll ruby_builtin_dlls\libwinpthread-1.dll --output ground.exe

The script works as expected when launched with ridk exec ruby ground.rb

Any suggestion? Thanks

Just in case it helps someone else, this is the command that ended up working

ocra ground.rb --dll ruby_builtin_dlls\libssp-0.dll --dll libgsl-27.dll --dll libgslcblas-0.dll --console --verbose --gem-full --add-all-core --gem-full=gsl

You need to copy libgsl-27.dll and libgslcblas-0.dll to the Ruby bin directory and not to ruby_builtin_dlls
