Here is another example of an Access violation error when building packages in Gentoo. This time the build process could not make a symbolic link in “/usr/bin” and the build process of the package failed with:
* ACCESS DENIED: symlink: /usr/bin/stransmit CMake Error: failed to create symbolic link '/usr/bin/stransmit': permission denied
A detail explanation is available in our first article on the subject here – Access Violation error, when compiling packages in Gentoo.
All packages are built in a sandbox and there is a sandbox configuration in
/etc/sandbox.d/00default
, which instruct the build process where could write. If you get such an error in 99.99% there is a bug in the package and if you do not want to wait for fixing it (report it!) you can manually edit the SANDBOX_WRITE variable and add the path, which causes the build failure. Build the package and remove the added path!!! Or you risk making your system less secure!
We have problem with building the package “net-libs/srt-1.3.1”

In the installation phase occurred the package failure leaving half installed package. So we edited the “/etc/sandbox.d/00default” and added “:/usr/bin” at the end of SANDBOX_WRITE:
SANDBOX_WRITE="/usr/tmp/conftest:/usr/lib/conftest:/usr/lib32/conftest:/usr/lib64/conftest:/usr/tmp/cf:/usr/lib/cf:/usr/lib32/cf:/usr/lib64/cf:/usr/bin"
Then rebuild the package with emerge and remove the added path “:/usr/bin”. This is a dirty workaround, but it will allow you to use srt (and as a dependency to another packages’ installation).
