problem building about loadlibrary HOT 13 CLOSED

Hmm, It should be in /usr/include/asm/unistd_32.h which gets included from asm/unistd.h.

I see your script does ln -s /usr/include/asm-generic /usr/include/asm, instead of using the arch ones.

If you really need to do that for some reason, you can probably add -D__NR_modify_ldt=123 to the Makefile CFLAGS in the peloader directory...

from loadlibrary.

If I don't include the ln -s I get the following error:

cc -O3 -march=native -ggdb3 -m32 -std=gnu99 -fshort-wchar -Wno-multichar -Iinclude -DNDEBUG -D_GNU_SOURCE -I. -Iintercept -Ipeloader  -c -o mpclient.o mpclient.c
mpclient.c:31:24: fatal error: asm/unistd.h: No such file or directory
compilation terminated.
<builtin>: recipe for target 'mpclient.o' failed
make: *** [mpclient.o] Error 1

from loadlibrary.

Hmm, does apt-get install linux-libc-dev:i386 provide it? (I'm not on Ubuntu right now)

from loadlibrary.

I tested on Ubuntu, I think apt-get install libc6-dev:i386 gcc-multilib is enough. I added that to the README.

from loadlibrary.

@blacktop You adding to this to your malice?

from loadlibrary.

Those packages are not found on ubuntu.

I made a small pull request with the packages that I did find that I think correlate with what you need?

from loadlibrary.

@thebetterjort yes I want to if it works.

I guess I probably need to use the GPL license on that plugin then?

@taviso what is your understanding of GPL with respects to me running your tool in a docker container, but not changing it in any way?

from loadlibrary.

I appended your license to mine, please let me know if that is satisfactory?

and again @taviso

you are THE MAN!!!

from loadlibrary.

Thanks, I guess we must be on different Ubuntu versions and the packages were renamed! I'll figure out which versions need which packages.

It's fine to run it and make any changes you like, the GPL only matters if you want to share your changes with other people, then the changes have to be GPL as well - that's basically it!

from loadlibrary.

@taviso @blacktop Agree! I'm just doing a straight build of this on Ubuntu and still getting the original error - but now I can't find the relevant package:

sudo apt-get update && apt-get install libc6-dev:i386 gcc-multilib

E: Unable to locate package libc6-dev:i386

from loadlibrary.

Sorry - just apt-get install gcc-multilib beat this one

from loadlibrary.

Apologies for the trickle feed - now mpclient won't build:

Any ideas? Thanks!

from loadlibrary.

Fixed via @blacktop 's Docker image - thanks + sorry!
