OK, this one is for you developer gurus. It is definitely off topic, and I deeply apologize for that, but I'm not sure where to post this. If you know of a better place please let me know. However, in this massive multideveloper yet beautifully orchestrated project I've come to know as gEDA, I'm guessing that someone out there can help me with this gnarly Makefile problem. The problem is this: I'm trying to use GSL (Gnu scientific library) in a project. In this source file network.cpp which sits in a directory called msvc is the line:
#include "gsl_eigen.h" // GSL eigenvalue routines The file gsl_eigen.h is in the directory in msvc/gsl/gsl, and has the following lines: #include <gsl/gsl_vector.h> #include <gsl/gsl_matrix.h> Those header files also live in msvc/gsl/gsl, but I can't figure out how to compile network.cpp and have gsl_eigen.h find them. My Makefile so far is: vpath %.h msvc msvc/gsl msvc/gsl/gsl ... CPP = g++ CPPFLAGS = -g -O2 -Wall -Wno-uninitialized ... network.o: network.cpp $(CPP) $(CPPFLAGS) -Imsvc/gsl/gsl -o $@ -c $^ and I'm getting these errors: g++ -g -O2 -Wall -Wno-uninitialized -Imsvc/gsl/gsl -o network.o -c msvc/network.cpp In file included from msvc/network.cpp:8: msvc/gsl/gsl/gsl_eigen.h:23:28: error: gsl/gsl_vector.h: No such file or directory msvc/gsl/gsl/gsl_eigen.h:24:28: error: gsl/gsl_matrix.h: No such file or directory ... Does anyone have any idea how I can get msvc/gsl/gsl truly included in the search for header source files so that gsl_eigen.h is happy? Again, I deeply apologize for this off topic post, but I'm don't know where else to turn! Many, many, many TIA, Craig
