The last PMIX import broke the master on all platforms that support visibility. I have pushed a patch that solves __most__ of the issues (that I could find). I say most because there is a big left that require a significant change in PMIX design.
This problem arise from the use of the pmix_setenv symbol in one of the MCA components (a totally legit operation). Except that in PMIX the pmix_setenv is defined in opal/mca/pmix/pmix2x/pmix/include/pmix_common.h, which is one of these headers that is self-contained and does not include the config_bottom.h, and thus has no access to the PMIX_EXPORT. Here are 3 possible solutions: 1. don't use pmix_setenv in any of the MCA components 2. create a new header that provides support for all util functions (similar to OPAL) and that supports PMIX_EXPORT 3. make pmix_common.h not self-contained in order to provide access to PMIX_EXPORT. Any of this approach requires changes to PMIX (and a push upstream). Meanwhile the trunk seems to be broken on all platforms that support visibility. George.
