compilation fail: duplicate listing of header files in src/Makefile.am & missing backslash

[Minh Van Nguyen]

Affecting revision: 2309

Checkout trunk of igraph 0.6 and run the following commands:

$ autoreconf --install
$ ./configure --prefix=/tmp/igraphusr
$ make && make install

Create a C source file named demo.c with the following content:

<quote>
#include <igraph.h>

int main(void) {
  return 0;
}
</quote>

Now compile the above program as follows:

$ gcc demo.c -I/tmp/igraphusr/include/igraph -L/tmp/igraphusr/lib -ligraph -o demo
In file included from demo.c:1:
/tmp/igraphusr/include/igraph/igraph.h:40: fatal error: igraph_complex.h: No such file or directory
compilation terminated.

The problem can be traced to the file src/Makefile.am, specifically the following section:

HEADERS_PUBLIC =../include/igraph.h ../include/igraph_memory.h \
  ../include/igraph_random.h ../include/igraph_types.h \
  ../include/igraph_vector.h ../include/igraph_matrix.h \
  ../include/igraph_array.h ../include/igraph_dqueue.h \
  ../include/igraph_stack.h ../include/igraph_heap.h \

  ../include/igraph_adjlist.h ../include/igraph_iterators.h \
  ../include/igraph_bipartite.h ../include/igraph_layout.h \
  ../include/igraph_centrality.h ../include/igraph_motifs.h \

  ../include/igraph_flow.h ../include/igraph_topology.h \
  ../include/igraph_foreign.h ../include/igraph_transitivity.h \
  ../include/igraph_games.h ../include/igraph_visitor.h \
  ../include/igraph_interface.h ../include/igraph_adjlist.h \
  ../include/igraph_progress.h ../include/igraph_constants.h \
  ../include/igraph_vector_pmt.h ../include/igraph_matrix_pmt.h\
  ../include/igraph_array_pmt.h ../include/igraph_dqueue_pmt.h\
  ../include/igraph_stack_pmt.h ../include/igraph_heap_pmt.h \
  ../include/igraph_vector_ptr.h ../include/igraph_spmatrix.h \
  ../include/igraph_strvector.h ../include/igraph_psumtree.h \
  ../include/igraph_sparsemat.h ../include/igraph_mixing.h \
  ../include/igraph_version.h ../include/igraph_blas.h \
  ../include/igraph_separators.h ../include/igraph_cohesive_blocks.h \
  ../include/igraph_statusbar.h
  ../include/igraph_lapack.h ../include/igraph_complex.h \
  ../include/igraph_eigen.h ../include/igraph_statusbar.h

Notice that there should be a backslash after "../include/igraph_statusbar.h". Put in the required backslash and again do

$ autoreconf --install
$ ./configure --prefix=/tmp/igraphusr
$ make && make install

will result in an installation error such as

/usr/bin/install: will not overwrite just-created `/home/mvngu/usr/include/igraph/igraph_statusbar.h' with `../include/igraph_statusbar.h'
make[3]: *** [install-includeHEADERS] Error 1
make[3]: Leaving directory `/home/mvngu/usr/src/igraph/src'
make[2]: *** [install-am] Error 2
make[2]: Leaving directory `/home/mvngu/usr/src/igraph/src'
make[1]: *** [install] Error 2
make[1]: Leaving directory `/home/mvngu/usr/src/igraph/src'
make: *** [install-recursive] Error 1

This is because some header files are listed more than once in the above "HEADERS_PUBLIC" section, in particular the following files are listed twice:

* igraph_adjlist.h
* igraph_progress.h
* igraph_statusbar.h

See the attached patch for a solution.

Thanks! Fixed in revision #2311 (0.6-main).
