I am trying to compile the glpkerl library on Ubuntu 11.10, but without success so far.
Since I am getting errors all the way, maybe there is something crucial that I am missing:
What I tried
My installed Erlang version is R14B02 (installed via the official apt repository of my distro).
Since my glpk version is newer in the official repo, I downloaded glpk-4.38 from here: http://ftp.gnu.org/gnu/glpk/. I don't want to install this version of glpk systemwide, so I create a directory, ~/opt, and use it in the following steps as the root for all libraries to be installed.
export MY_PREFIX=$HOME/opt
mkdir $MY_PREFIX
cd /tmp
curl http://ftp.gnu.org/gnu/glpk/glpk-4.38.tar.gz | tar zx
cd glpk-3.48 && ./configure --prefix=$MY_PREFIX && make -s && make -s install
Next, I download the glpkerldrv and try to install it:
cd /tmp
curl http://glpkerl.googlecode.com/files/glpkerldrv-4.38.0.tar.gz | tar xz
cd glpkerldrv-4.38.0
./configure --prefix=$MY_PREFIX LDFLAGS="-L$MY_PREFIX/lib" CPPFLAGS="-I$MY_PREFIX/include"
make -s
Apparently something went wrong while using make. I disabled the transformation of compiler warnings to errors by using --disable-hardcore during configure, as stated on the glpkerl install wiki. But even then, the following undeclared identifier error still remains:
handlers.c: In function decode_from:
handlers.c:3310:29: error: INT_MAX undeclared (first use in this function)
handlers.c:3310:29: note: each undeclared identifier is reported only once for each function it appears in
Apparently the perl script that generates handlers.c file should also include the limits.h. I corrected it by adding the following (I have no experience with C so I am unsure if this is the right way to do it):
--- a/src/make-handlers
+++ b/src/make-handlers
@@ -52,6 +52,10 @@
my ($name, $values) = @_;
print <<EOD;
+#include <limits.h>
+EOD
+
+ print <<EOD;
#define deserialize_$name(buf, buflen) \\
({ \\
uint8_t byte; \\
Now the building works (with --disable-hardcore, although I don't think the warnings are to be ignored, see attached file), and I can execute a make, make check, and make install, which I did.
I am stuck in the second part though:
cd /tmp
curl http://glpkerl.googlecode.com/files/glpkerl-4.38.0.tar.gz | tar xz
cd glpkerl-4.38.0/
./configure --prefix=$MY_PREFIX LDFLAGS="-L$MY_PREFIX/lib" CPPFLAGS="-I$MY_PREFIX/include"
PKG_CONFIG_PATH=$MY_PREFIX/lib/pkgconfig make -s
PKG_CONFIG_PATH=$MY_PREFIX/lib/pkgconfig make -s check
while building seems the work fine, the check fails because of a dialyzer error:
dialyzer: Could not find the PLT: /home/my_user/.dialyzer_plt
Apparently, we can pass a DIALYZERFLAGS to the makefile, which I did:
DIALYZERFLAGS="--build_plt" PKG_CONFIG_PATH=$MY_PREFIX/lib/pkgconfig make -s check
and here is where I am unsure how to proceed
after executing the last command, I get the following error:
dialyzer: {dialyzer_error,"Byte code compiled with debug_info is needed to build the PLT"}
the strange thing is, that the +debug_info parameter is passed to the erlang compiler apparently, as found in the Makefile.opt file.
I stopped investigating any further, because I am not sure how I can solve this at all with my current environment; am I missing something obvious here? Thanks!
