Depending on which version of the motor module you are using you may need to edit motorApp/Makefile to uncomment the line to build the OmsSrc directory.  That is the correct way to do it, then you won't have to copy the source files to your application directory.

Subject: ??: MAXvSetup is an undefined symbol

If i don't compile the source file , there will be some error about oms:

ld < mx.munch
Undefined symbol: pvar_dset_devOMS (binding 1 type 0)
Undefined symbol: pvar_dset_devMAXv (binding 1 type 0)
Undefined symbol: pvar_drvet_drvOms (binding 1 type 0)
Undefined symbol: pvar_drvet_drvMAXv (binding 1 type 0)
Undefined symbol: pvar_dset_devOms58 (binding 1 type 0)
Undefined symbol: pvar_drvet_drvOms58 (binding 1 type 0)
ld error: Module contains undefined symbol(s) and may be unusable.
value = 0 = 0x0

Then i check the files, i did not find the oms library. So i have to compile the source directly. The reason for my problem is i don't have oms library after i compiled the motor support in the lib or other directory.

You are doing things differently than we normally do.  You are compiling the motor files (motorRecord.cc, devMAXv.cc, etc.) directly as part of your application with the lines like:

mx_SRCS_vxWorks += motorRecord.cc motordevCom.cc motordrvCom.cc

but you are also including those same routines again via external libraries with lines like:

mx_LIBS += motor
mx_LIBS += SoftMotor

As noted yesterday you are not including oms as an external library, which you should.

I suggest that you do not compile the motor or oms code again as part of your application, but rather just include the libraries from the motor module.

This works fine for me under vxWorks with the vxWorks shell, I do not have problems with C++ name mangling and MAXvSetup works with no problems.

Subject: MAXvSetup is an undefined symbol

Hello,everyone.

I have two application of oms motor and hytec adc, but i only have a VME crate. So i need to merget the two application to one ioc. The oms motor application from
synApps and hytec 8401 work well respectively. So i use the makeBaseApp.pl to produce a new application and revise the makefile, and copy the source file to the
corresponding directory. The compile is ok, i can get the munch and st.cmd files.

When download st.cmd to the vme, there are will problems. It is said the MAXvSetup is an undefined symbol. It is very strange. I insert the hytec8001 and 8401 in the
first and the VME in the third.

Please give me some advice and idea.

Thanks.
