Make library independent executable files.

mkblob

Tool to make executables independent from libraries.

Make with makeall_el8.sh on x86_64 version of CentOS 8 or Red Hat Enterprise 8.

You might have to tweak the script to make it compile on other distributions. Also glibc-static is needed to compile. (dnf install glibc-static) Precompiled binary is included in directory binary_x86_64 as well as rpm and deb files.

mkblob should run on any x86_64 as it is statically compiled and includes all files it needs.

With mkblob you can make new library independent executable which you can move around different Linux distributions. It will gather all the dependecies it needs to run and other files your program uses.

Project was originally started to make opencv programs able to run without recompiling/rebuilding/installing.

Example: mkblob /bin/ls -o ls.blob -static

mkblob can be used on not only binaries, but scripts as well, like shell, perl and python and so on. If you need or want to pass arguments to your (binary) program you should create a script which does this and then run this script with mkblob.

There is also a Raspberry Pi version at: https://github.com/sigurd-dev/mkblob-rpi

mkblob's Issues

Uncaught exception: Couldn't create SDL window?

I'm really new to linux packaging. I compiled https://github.com/jorio/Bugdom on Tumbleweed, ran mkblob /home/tuxpeng/Bugdom/build-release/Bugdom -o Bugdom.static -static The result ran great on the host system. Then I tried the binary on a Ubuntu 20.04 VM

Uncaught exception: Couldn't create SDL window

So, I tried compiling o n Ubuntu and running on Tumbleweed, same error. Is there any way to make this work?

Build from OpenSUSE: https://filedn.com/lHGef0SOQKnBTotcJeEfshJ/Games/Bugdom/Bugdom.tar.gz

Race condition: Execute the blob concurrent: Failed.

Hi there, it works all fine here, but only if i not execute the generated blob concurrently.

The Error happens on any generated ELF/Blob.

For example:

mkblob /bin/echo -o echo-blob -static`
parallel --jobs 10 ./echo-blob ::: {1..100} > /dev/null
# this will execute echo-blob 10 times parallel ... on ie. Ubuntu you can install the 'parallel' Tool with: apt-get install parallel

Many Errors like.. see below:

It looks that the temporary folder should be random and unique for each execute. Currently the temporary folder ist always the same which triggers the racecondition.

Is there any fix for it?

Thank you
