Safety of PDB files persistence in General Discussion Posted January 23 · Report reply Hi Martin, Let me answer to your questions referring to their numbers only. 1.2. Yes. In fact, glibc is just a standard system library so any linux application depends on it. 1.3. Yes, but note that there is section Compliance Tests. Given the large variety of linux distributions we cannot guarantee totality of support. Also note that if you're building a native (ex. C/C++) library it is not JET-compiled and thus might require higher version of glibc/kernel depending on its compiler settings and build environment. 1.4. JET-compiled applications/libs are compiled by `jc` and linked by `xlink` -- internal compiler and linker placed in $JET_HOME/bin. 2.1. Yes. 2.2.2. Yes, that should work. But note that in JET 15 (scheduled to May) we plan to rework smart recompilation and some things regarding *pdb might change. 2.3. All of those files are used at some step of build process. Removing some of them might result in partial or full recompilation. For example in obj.zip all object files (machine code from compiler) are written and from them the linker composes resulting exe/so. Kind regards, Igor Jorch, Excelsior Support.
