Where can I find the C compilation flags for IDL 3.6 (or any version)
for gcc and/or g++ for use in a call_external?
Thanks,

Hello fellow GEMS person.
I've used the attached makefile successfully to produce a "csvd.so" to
be used in a CALL_EXTERNAL as:
foo = CALL_EXTERNAL(!xdir+"/csvd.so","csvd",c,mmax,nmax,m,n,ip,nu,nv,s,u,v)
This uses file "csvd.cc" as a C++ wrapper for the main code in FORTRAN
file "dsa_csvd.f".
We are using fairly old SW, but it works:
SunOS 4.1.2 and its bundled loader/linker
GNU C 2.6.3
GNU libg++ 2.6.2
GNU make 3.73
Sun SPARCompiler Fortran 2.0.1
IDL Version 4.0.1
