Linker can not find __imp_clock and __imp_time64 when building a sample of GTSAM

Asked 2021-Jul-11 at 14:06

I build GTSAm in windows and now I am trying to build sample application with it.

The sample application is very simple (it is part of GTSAM) but when I run it, I am getting this linker error:

__imp_ prefix in unresolved external runtime library symbol from the linked library means the library was built with DLL runtime (/MD in C++ -> Code Generation -> Runtime Library).

If you build the application with static runtime (/MT) the symbols from the DLL runtime will be unresolved. Runtime settings should be the same for all compilation units.

How to detect in bash script or docker file if the build is taking place on a docker hub server?

Asked 2020-Jun-22 at 20:46

So I have a docker file which compiles and installs gtsam with cython wrapper. The docker setup works fine on the local machine but it runs out of memory when building on docker hubs automated build. I believe I can reduce the memory usage by changing to make -j1, but I'd still like faster builds when performed locally. I tried accessing the sys/fs/cgroup/memory/memory.limit_in_bytes which shows to be 9223372036854771712 way more then the 2G limit on the servers.

Is there a way to detect if the build is taking place through the automated build and accordingly adjust the -j flag

Docker Hub sets environment variables that are available at build time.

For example, you can test if the build process happens on Docker Hub by checking if SOURCE_BRANCH is set.

The full list of env variables can be found here.

Your library uses Eigen3 library, which is also part of gtsam library used in the tests. You need to make sure that in both cases the same Eigen3 library is used, otherwise subtle bugs could happen (like the one you observe).

Technically, your library and gtsam-based test are separate objects files, so they are compiled independently and both of them are correct.

It is a linker who could perform unwanted optimizations like merging functions from these object files. E.g. in case these functions have the same name. If you find a way to forbid such sort of optimizations for the linker, then resulted test could work correctly even in case of incompatible Eigen3 libraries used for your library in by gtsam.

However, disabling linker optimizations is a very subtle way from the view of stability of your project. Use this way only as the last resort.
