Use of --gc-sections
haampie opened this issue · comments
Commit 0f020fd changed the default of jasper to use the --gc-sections linker flag.
The project here: https://confluence.ecmwf.int/display/ECC depends on those symbols (for example jpc_encode) that are pruned by the linker.
Wouldn't it be better to leave the default to JAS_ENABLE_HIDDEN=OFF?
The decision to make hiding symbols the default behavior is deliberate. Library users shouldn't rely on the symbols that are would be hidden by this option, as such symbols are not part of the official library API and could change or be deleted without warning. What symbols are you relying on that are hidden by default (just to be sure that something that is part of the API was not accidentally marked as hidden)?
Since I have not received any response in over a month, I am going to assume that the problem is not due to a JasPer library API symbol being accidentally marked as hidden when it should not be (i.e., the problem is not due to a bug in JasPer but rather due to the library user making use of symbols that are not part of the JasPer library API). Since this is not a bug, I am going to close this issue.
