[gmx-developers] Re: libgmxana.so dependencies

[Roland Schulz]

Hi,

I found a solution:
diff --git a/src/tools/Makefile.am b/src/tools/Makefile.am
index 0b03eb1..ffd8d88 100644
--- a/src/tools/Makefile.am
+++ b/src/tools/Makefile.am
@@ -6,8 +6,8 @@ AM_CPPFLAGS = -I$(top_srcdir)/include
-DGMXLIBDIR=\"$(datadir)/top\"

 lib_LTLIBRARIES = libgmxana at LIBSUFFIX@.la

-libgmxana at LIBSUFFIX@_la_LIBADD         =
-libgmxana at LIBSUFFIX@_la_DEPENDENCIES   =
+libgmxana at LIBSUFFIX@_la_LIBADD         = ../gmxlib/libgmx at LIBSUFFIX@.la
../mdlib/libmd at LIBSUFFIX@.la
+libgmxana at LIBSUFFIX@_la_DEPENDENCIES   = ../gmxlib/libgmx at LIBSUFFIX@.la
../mdlib/libmd at LIBSUFFIX@.la
 libgmxana at LIBSUFFIX@_la_LDFLAGS        = -version-info
@SHARED_VERSION_INFO@

Is it correct to add it to both LIBADD and DEPENDENCIES? Any reason not to
commit this?

Roland
