Small progress, both gcc and cl compilers create and object files from the sources, however it does not proceed to the link phase. See what i mean in the following.
IDL script for gcc compiler:
make_dll, 'mg_callex_total', 'IDL_Load',export_rtns, $
INPUT_DIRECTORY=working_directory+'\test_call_external' , CC='gcc -c %C', $ ;
generates:
gcc -c " C:\USERS\NEIL\DOCUMENTS\IDL\test_call_external\mg_callex_tot al.c "
Could Not Find C:\Users\Neil\Documents\IDL\test_call_external\IDL_Load_4592 _NEIL-THINK.exp
Could Not Find C:\Users\Neil\Documents\IDL\test_call_external\IDL_Load_4592 _NEIL-THINK.lib
Could Not Find C:\Users\Neil\Documents\IDL\test_call_external\mg_callex_tot al_4592_NEIL-THINK.obj
------------------------------------------------------------ -
IDL script for cl compiler:
make_dll, "mg_callex_total", "IDL_Load", export_rtns, $
INPUT_DIRECTORY=working_directory+"\test_call_external", CC="cl %C %O"
generates:
mg_callex_total.c

/out:mg_callex_total.exe

Could Not Find C:\Users\Neil\Documents\IDL\test_call_external\mg_callex_tot al_4592_NEIL-THINK.obj
------------------------------------------------------------ --------------
However, for some reason what should be the output file 'IDL_Load' it appends on to the end of this _4593_NEIL-THINK, which is the name of my machine on the net. I take it this should not happen? However, no such output file appears to be generated.
Any clues why this does not proceed to the link phase?
many thanks,
neil
