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. $ make make  all-recursive make[1]: Entering directory `/home/user/tmp/pacman' Making all in lib/libalpm make[2]: Entering directory `/home/user/tmp/pacman/lib/libalpm' Making all in po make[3]: Entering directory `/home/user/tmp/pacman/lib/libalpm/po' make[3]: Leaving directory `/home/user/tmp/pacman/lib/libalpm/po' make[3]: Entering directory `/home/user/tmp/pacman/lib/libalpm' make[3]: Nothing to be done for `all-am'. make[3]: Leaving directory `/home/user/tmp/pacman/lib/libalpm' make[2]: Leaving directory `/home/user/tmp/pacman/lib/libalpm' Making all in src/util make[2]: Entering directory `/home/user/tmp/pacman/src/util'   CCLD   testpkg ../../lib/libalpm/.libs/libalpm.so: undefined reference to `MD5_Init' ../../lib/libalpm/.libs/libalpm.so: undefined reference to `MD5_Final' ../../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 `MD5_Update' ../../lib/libalpm/.libs/libalpm.so: undefined reference to `SHA256_Final' 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:

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. Allan

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).

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

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