Hello everyone,

 

I got the EPICS module “std” from github (git clone https://github.com/epics-modules/std.git). From its configure/RELEASE, my initial thought was that the module should work with base-3.15.3 & asyn-R4-30. I tried that out and indeed the module “std” is built successfully against base-3.15.3.

 

Since we are still using base 3.14.12.3 at NSLS-II and we have lots of Debian packages already built for EPICS, I’d like to take the advantage of this existing infrastructure so that I am trying to build "std" against base 3.14.12.3 (provided by the Debian packages). The build failed when it tried to build the ioc application “stdApp”. It seems the library “libstd.*” is not found (not included in the path) although I can clearly see “lib/linux-x86_64/libstd.*” is actually generated.

Then, I typed “make” again. The built passed and the ioc application “stdApp” was generated. See below. During the second “make”, we can see a new path (-L/epics/iocs/vme-03idc-testing/std/lib/linux-x86_64) is added and that path is where the generated libraries “libstd.*” are located.

I guess there must be some changes/improvements on the Base build rules. I searched in tech-talk and tried all kinds of configurations as discussed at https://epics.anl.gov/tech-talk/2016/msg01063.php, but still could not build the module “std” by the first “make”.

Could anyone tell me how to solve this build problem if I really want to build “std” against base 3.14.12.3?
