Building under Ubuntu 12.04 (32-bit) - Error Messages

[jeremysolarz]

I build pwntcha like os

./bootstrap
./configure
./make

Get the following error after make

Any hint what could be the reason for this?

I have the same problem as you.

I don't have a Ubuntu box at hand and cannot test. Looks like the new GCC in your system deprecated implicit declaration of sqrt etc. functions. Try to include the math header <math.h> in the reported files (decoder.c etc.) and recompile. Please fork and send a pull request.

[samsemilia7]

To solve that problem you should try the following steps:

• run :
  ./bootstrap
  ./configure
• change into pwntcha/src
• run make till the error occurs
• then run the following command:
  g++ sdl-config --cflags -Wall -O6 -g -O2 -o pwntcha pwntcha-main.o pwntcha-filter.o pwntcha-font.o pwntcha-image.o pwntcha-easter-eggs.o pwntcha-test.o authimage/libdecoder.a clubic/libdecoder.a java/libdecoder.a linuxfr/libdecoder.a livejournal/libdecoder.a lmt/libdecoder.a paypal/libdecoder.a phpbb/libdecoder.a scode/libdecoder.a slashdot/libdecoder.a ticketmaster/libdecoder.a tickets/libdecoder.a vbulletin/libdecoder.a xanga/libdecoder.a sdl-config --libs -lSDL_image

The command is mostly the same, except for the compiler (used g++) and the compiler flags are at the end.
After that, you will have your executable :D ( Tested on a ubuntu 12.04, 64bit).

getting configure.ac:5: option tar-ustar' not recognized on fedora when ./bootstrap

[samsemilia7]

maybe there is a space missing. try changing the line to tar -ustar

[kelonye]

@samsemilia7 maybe tar-ustar option isn't in automakev1.7 and below.

[djg123]

@samsemilia7 I am getting

/usr/bin/ld: cannot find -lSDL_image
collect2: ld returned 1 exit status

[iveney]

That means you need to have SDL_image library installed.

Managed to build pwntcha in cygwin!

So I have done exactly what samsemilia7 told to do, but in my case I use imlib2 so I run

g++ imlib2-config --cflags -Wall -O6 -g -O2 -o pwntcha pwntcha-main.o pwntcha-filter.o pwntcha-font.o pwntcha-image.o pwntcha-easter-eggs.o pwntcha-test.o authimage/libdecoder.a clubic/libdecoder.a java/libdecoder.a linuxfr/libdecoder.a livejournal/libdecoder.a lmt/libdecoder.a paypal/libdecoder.a phpbb/libdecoder.a scode/libdecoder.a slashdot/libdecoder.a ticketmaster/libdecoder.a tickets/libdecoder.a vbulletin/libdecoder.a xanga/libdecoder.a imlib2-config --libs -lImlib2

and I got the error

$ g++ imlib2-config --cflags -Wall -O6 -g -O2 -o pwntcha pwntcha-main.o pwntcha-filter.o pwntcha-font.o pwntcha-image.o pwntcha-easter-eggs.o pwntcha-test.o authimage/libdecoder.a clubic/libdecoder.a java/libdecoder.a linuxfr/libdecoder.a livejournal/libdecoder.a lmt/libdecoder.a paypal/libdecoder.a phpbb/libdecoder.a scode/libdecoder.a slashdot/libdecoder.a ticketmaster/libdecoder.a tickets/libdecoder.a vbulletin/libdecoder.a xanga/libdecoder.a imlib2-config --libs -lImlib2

collect2: error: ld returned 1 exit status

after installing the missing libraries and running the command again, pwntcha.exe was successfully created.

@jeremysolarz I have the same problem as you, now. OS: ubuntu12.04. I think cywin is not proper for development, but i can't transfer it to Linux

[2called-chaos]

With your help I was able to build it on 14.04 as well, thanks!
