Segmentation fault (core dumped)

Segmentation fault (core dumped) when running apache2nginx -f /var/apache2/conf/httpd.conf

[avelis]

+1 Running Mac OS X Mavericks. From what I have been reading. It would appear that the program has a bug in it. I had to compile and run it the my local hardware. I am unsure if my machine's hardware is the root of the issue or the source code itself.

Ok. Upon further investigation I was able to get this tool to work. The caveat is that it has to run on a Ubuntu server or unix server. Even then I still have to compile from source and install it in /usr/local/apache2nginx as per the project page documentation. As a Mac OS X user, without a Ubuntu server ready, I had to leverage a local virtual Ubuntu server via Vagrant to convert my apache configurations. I know this isn't a solution to the problem above, but an alternative for others who might land here.

tl;dr

1. Use Vagrant to create an Ubuntu server.
2. Sync your Apache confs that you want to convert onto that same server.
3. Install apache2nginx via source (Main project page provides docs to do this).
4. Use apache2nginx to convert your confs to be nginx compliant.

Tried on a Majaro system and got a core dump. What does ubuntu have that is missing in manjaro?

[gaby64]

also getting segfault on ubuntu

It indeed segfaults:

I have a fork that works, updated apr and included Reeds mods

@gaby64 even using your repo, I kept getting libtool generated with CRLF issues (^M). Running a recursive dos2unix -f got me a fixed libtool, and consequently a proper configure stage.

However, the end result is a compiled and working binary. Thanks!

that might be an issue with your git config, I cloned my repo an had no issue on Ubuntu 18.10

running file -- * shows no file with crlf endings

This is Sooo broken.

Was wishing this would work, tried everything that was commented here, was able to compile and run on ubuntu, but also got Seg Fault. Might need to write my own in java, stay tuned.

Hi gaby64 -- How can I build your solution? The READ.ME file on your fork is identical to the original -- so the the same files will be compiled.

Thank you

[gaby64]

download source files from my fork ./configure make && make install

[steelliberty]

download source files from my fork ./configure make && make install

Thank you for the help .. making progress -- I am now getting the error message

run buildconf

[steelliberty]

run buildconf

Okay .. I had to install libtool and buildconf ran without errors .. then I did ./configure make && make install

resulting in this error

install expat lib or package for your distro

please do the research, I only intended to provide patched code that worked for me, not compile support. it may not even work anymore, I could check tomorrow.

[steelliberty]

I got it running ... the config files of the latest apache2 server is largely unconvertable, numerous messages in the new conf file . Worse yet the .htaccess files in word press site can be enormous which presents a new conversion issue.

I am sorry for the intrusion and thank you for your help.

I am going to start from scratch --
