You're going to have much better luck just transferring the pacman XZ zipped package to the machine and unzipping it directly in '/', then removing the /.PKGINFO and /.INSTALL file it will leave behind.

I would like to modify the sources and understand the pacman code. so compiling the sources is a necessary.

You probably need the gettext development package installed.

I have installed the gettext package version 0.8.1.1-3ubuntu1 and it compiles the files in the **pacman/lib/libalpm/po** directory. Thank you for the info.

But the make file reports error in **pacman/src/util** directory.

Seems like MD5 related library has to be installed. I do not know which one to install. I was expecting ./configure scritpt to report about these required libraries.

Br, Talespin

sounds like you didn't google, since googling this issue shows me that

people tried to include openssl.h. So the issue could be that you are missing openssl-dev. Take a look at pacman's dependencies with:

I initally thought that might be problem and looked at the ./configure output which reported (also libssl-dev is installed) ....... checking whether to link with libssl... yes checking for MD5_Final in -lssl... yes ......

Found library "gpgme" was missing. After installing it below is the following error from signing.c file

That requires gpgme-1.3.0 which was released over two years ago...

That is entirely unrelated to your issue with "undefined reference to `MD5_Init'".  Attach your configure and build output if you want help with that.

Now finding which library contains **MD5_Init** symbol using the below

bash commands

for i in `find /usr/lib -type f -name '*.so.*'`; do      nm -D $i | grep MD5_Init;      if [ $? -eq 0 ];

then

echo $i;      fi; done

Output:-

====== 00004320 T MD5_Init /usr/lib/i386-linux-gnu/libgnutls-openssl.so.26.16.14

No, that's the wrong library -- we link against openssl's libcrypto. Is libssl-dev installed?

NB: I've yet to be able to build pacman successfully against anything involving gnutls, and i've even had build failures when libarchive linked to gnutls (though that may have been resolved by binutils 2.22).

Now linking with the libgnutls-openssl library

$ /bin/bash ../../libtool --silent --tag=CC   --mode=link gcc -std=gnu99 -pedantic -D_GNU_SOURCE -g -O2 -Wall   -o testpkg testpkg.o ../../lib/libalpm/.libs/libalpm.la -lssl -larchive -lm -lgnutls-openssl ../../lib/libalpm/.libs/libalpm.so: undefined reference to `SHA256_Init' ../../lib/libalpm/.libs/libalpm.so: undefined reference to `SHA256_Update' ../../lib/libalpm/.libs/libalpm.so: undefined reference to `SHA256_Final' collect2: ld returned 1 exit status

Only MD5_* symbols are able to find by ld.

Problem with SHA256_* symbols. Finding the **SHA256_Init** symbol using the above bash commands outputs.

00187db0 T SHA256_Init /usr/lib/libgs.so.9.04

This is ghostscript... I assure you we don't link against this. It should all be covered by openssl.

Trying to link with the libgs.so.9.04 library gives the following error.

$ /bin/bash ../../libtool --silent --tag=CC   --mode=link gcc -std=gnu99 -pedantic -D_GNU_SOURCE -g -O2 -Wall   -o testpkg testpkg.o ../../lib/libalpm/.libs/libalpm.la -lssl -larchive -lm -lgnutls-openssl -lgs /usr/bin/ld: cannot find -lgs collect2: ld returned 1 exit status

No idea why the linker fails to find the libgs library.

Finally managed to compile in ubuntu-11.10.

Seems the problem was the Makefile generated by the configure script for the **libalpm** does not add the  **libcrypto** as dependency in the LIBS variable.

Below is the steps.

I have used the git commit e6f72c61a098b52ea29e54b8eb4739a2ff81e6b0in

repo git://projects.archlinux.org/pacman.git

1) $ git clean -xfd; ./autogen.sh && ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \

--enable-git-version --enable-debug --without-gpgme

2) cd lib/libalpm

3) In the Makefile replace line

LIBS = -lssl -larchive -lm

with LIBS = -lssl -larchive -lm -lcrypto

4) cd ../../ && make
