Failure to compile EQEmu on Slackware 14.2

[Myserk]

Hi,

I've been trying to get EQEmu to compile on Slackware 14.2 over the past few days, and have finally hit a dead end after sorting out a multitude of issues. I'm out of ideas on where to look for a solution to this one.

The problem in question:

[ 90%] Linking CXX executable ../bin/zone
/usr/local/lib/perl5/5.32.1/x86_64-linux-ld/CORE/libperl.a(pp.o): In function `Perl_pp_crypt':

Or from a more verbose log:

I think it may be a linker issue in glibc? but that's almost a guess on my part after reading various items which were somewhat but not quite related. Even if it is, I have no idea how to go about fixing that.

Gcc version is 5.5.0 if that's relevant.



Additional info just in case:

I wish I could help. Linux, although far more stable than Windows can be very fickle... Sometimes simply trying an install again works, and who knows what kind of bug was being encountered... I will ask, why use Slackware at all? It's soundly tested in both Ubuntu and Debian. No reason to reinvent the wheel since they're all freely distributed operating systems.

Its been a while since ive compiled eqemu, however it is saying you need the crypt module for perl

make sure you have libssl-dev and openssl-devel

also identify any perl-Crypt packages (libcrypt?)

like..:
https://pkgs.org/download/perl-Crypt-DES

[demonstar55]

Looks like you built perl yourself, something most likely went wrong there is my guess

[Myserk]

Thanks for the pointers! No luck so far, but at least I've got some fresh ideas to try.

In short, because it's what I have installed & is a remote headless server. I have no idea why I originally picked Slackware (just a glutton for punishment I guess!), but I originally started toying with Linux & Slackware about 20 years ago by putting together a server. I've continued to simply migrate the vast majority of it with each hardware failure across 2-3 machines ever since. I could just add another virtual machine to it & run Ubuntu from inside that in order to compile + run EQEmu, but I always wind up learning a lot more by taking the difficult route with Linux.

To the best of my knowledge, Slackware doesn't differentiate between just installing a package & installing all the devel/headers etc. I believe if something is installed, it throws the whole lot in. I definitely have openSSL installed as I control the box via SSH. It also has an https capable apache server running, among other things which rely on SSL.

I was hopeful with the various perl crypt modules (after 60+ minutes of cpan installing an awful lot of them), but the error seems to remain the same unfortunately. I also installed the package provided in your link, just for good measure.

I did run a small script to test the crypt function in perl (both before and after adding a stack of modules), and it seemed to function without any issue.

Is that because Perl is located in /usr/local? Slackware does that with the stock version as far as I'm aware. I vaguely remember reading an explanation as to why & the reasoning for it, but couldn't provide a link as I came across it while troubleshooting one of the various other issues I encountered in attempting to compile EQEmu. I may be a bit confused/mixing up issues there though, so that might not be entirely accurate.

I'm fairly certain I'm just running the stock Perl for 14.2, upgraded via slackpkg+, although I do remember messing with compiling Perl myself (and having it fail to do so) before simply using slackpkg+. I'll definitely have to look into confirming that however.


-edit: Scratch that. Turns out I somehow managed to get the latest version of perl compiling & then proceeded to install it, give it priority over the still-installed system default, and additionally mess up a bunch of pathing on the user account being used to compile the emulator! I've removed that version, restored the system default, removed the inadvertent .bashrc modifications and learnt a bit more about the history of /usr/local!

It now builds flawlessly. Thanks again.


In the incredibly unlikely circumstance that somebody else comes looking for help with building on Slackware, the only part I can remember that had me stumped for a while (other than the Perl issue thanks to my own idiocy!) is a modification which you may need on the CMakeLists.txt file. You'll probably need to add in the following code, I think it was to do with the newer version of cmake & possibly boost. You'll know the problem when you see it anyway.

IF(POLICY CMP0057)
        CMAKE_POLICY(SET CMP0057 NEW)
ENDIF()

[demonstar55]

I'll set up a slackware VM and see if I run into that CMake issue you mention.

Using Boost version 1.75.0 and Cmake version 3.5.2.

This is what I see if I don't add in the aforementioned modification.

See also "/home/eqemu/src2/build/CMakeFiles/CMakeOutput.log".

I don't believe it appeared on the Slackware 14.2 stock version of cmake (approximately version 3.1? from memory), but I upgraded cmake in the process of trying to get the compilation to work & then had to solve the above issue.



Additionally (and far less critically as they're only warnings, but may become an issue in the future), I saw a fair number of these during the compile. I'm pretty sure they didn't occur when I tried with an older version of Boost initially.
