linux compile (almost) (by John Griessen)
Hi,

I am trying out recommendations to compile on debian linux
by setting some flags, and using configure settings for static building.

I had changed Makefile.am per http://www.circuitousroot.com/...ing/useful/packages/index.html but was getting errors suggesting a problem of
running make in the solvespace dir, so I changed to using a separate
build dir, and also started from a fresh copy of https://gitorious.org/solvespace/solvespace.git

I run .autogen.sh in solvespace then do not touch it further.

I set environment vars:
libs=-lGL
LDFLAGS=-lGL


from the build dir, I run:

./solvespace/configure --enable-shared=no --enable-static=yes

make runs without errors:

Has a GUI been made? Where is its executable if so?

The gui has not been made. Having a look at contraint.cpp shows that that specific object file will not have the function in question defined if LIBRARY is defined. Your earlier build messages show it was defined.

delete contraint.o and rebuild it without -DLIBRARY and the rest should finish

$ locate constraint.o
/usr/local/src/solv-build/src/constraint.o
/usr/local/src/solv-build/src/drawconstraint.o

Delete both files, or just /usr/local/src/solv-build/src/constraint.o
?

"rebuild it without -DLIBRARY and the rest should finish "

Do you mean redo the configure also, or just the make?

/usr/local/src/solv-build/src/constraint.o

Its been a while since I've built on linux so I'm guessing the configure but I'm not seeing where -DLIBRARY is getting generated from.

you may be able to edit one of the generated Makefiles and fix that. I never mastered learning the autoconf/automake system so I'm at a bit of a loss

Today I noticed some of the library flag specs have been added to the makefiles, so I got a fresh copy of the repo, ran autogen.sh left that dir and configured from a separate build directory:

Any ideas? Should I try deleting .o files for the fltk packages, leaving only the .a
files and compile static linked again?

So now I need to repair my fltk install, ( I need it for other programs)
and go back to trying to get a samba share working for a Win7 VM...

(no subject) (by Roland Lutz)
The GUI application and libslvs share some object files (constraint.cpp, constrainteq.cpp, entity.cpp, expr.cpp, system.cpp, util.cpp) which are compiled twice with different preprocessor flags. Usually, per-target compilation flags cause object files to be renamed, so you get solvespace-constraint.o and libslvs_a-constraint.o etc. In this case, the compilation runs are controlled by two different Makefiles, so using different AM_CPPFLAGS seems to work at first. However, when building libslvs, the object files for use with the GUI application are overwritten, so a subsequent “make install” will fail.

Since libslvs and the CDemo application aren't installed, you can simply remove the object files and recompile the GUI.
