I would use a configuration file. Copy
/usr/lpp/cbclib/xlclang/etc/xlclang.cfg into one of your directories and
either set the XL_CONFIG environment variable or include it with the -F
compiler option. Add your data set to the syslib_x concatenation.

I don't know how the xclang++ line got mangled, but it's really just one line -
NOT three invocations of xclang++!
Guessing it's something about the ++ and the listserv, let's try it again substituting
"FRED" for "xclang++"
FRED -v -Wl,MAP,LIST=ALL,XREF -obin/zprotect obj/zprotect/zprotect.cpp.o
lib/libsapi.a lib/libvtk-core.a /usr/lib/GSKCMS64.x /usr/lib/GSKSSL64.x

Subject: How to specify logical SYSLIB when linking with xclang++ under uss
I am having a problem using xlclang++ to link my program on uss. I have
unresolved references, but I actually know where the modules that are needed
are located - I am just unable to express that information to the binder.
As an example, CSNERNG is located in "CSF.SCSFMOD0", but isn't found because
the default SYSLIB is just the concatenation of CEE.SCEEBND2 with SYS1.CSSLIB. I need to
logically add CSF.SCSFMOD0 to that concatenation.
I discovered that with the '-v' switch, I can get xlclang++ to emit both the pseudo-JCL
it would use and the "export"s of environment variables, and, from that output,
I discovered that the variable _CXX_L6SYSLIB is what I supposedly need to set - but
setting it and exporting it prior to issuing my make command doesn't have any effect -
the unresolved reference still occurs, and the generated pseudo-JCL does not include my
addition to the concatenation. (BTW the Unix System Services Command Reference confirms
that _CXX_L6SYSLIB is the correct variable for an lp64 invocation.)
The command that I am using for the link is:
xlclang++ -v -Wl,MAP,LIST=ALL,XREF -obin/zprotect
xlclang++ obj/zprotect/zprotect.cpp.o lib/libsapi.a lib/libvtk-core.a
xlclang++ /usr/lib/GSKCMS64.x /usr/lib/GSKSSL64.x
The export I am doing first is:
export _CXX_L6SYSLIB=CEE.SCEEBND2:SYS1.CSSLIB:CSF.SCSFMOD0
and yet my generated pseudo-JCL is still:
...
//LINKEDIT EXEC PGM=LINKEDIT,
// PARM='AMODE=64,TERM=YES,
// DYNAM=DLL,ALIASES=NO,UPCASE=NO,
// LIST=OFF,MAP=NO,XREF=NO,INFO=NO,MSGLEVEL=4,
// REUS=RENT,EDIT=YES,AC=0,CALL=YES,CASE=MIXED
// ,MAP,LIST=ALL,XREF
// ,LP64'
//SYSLIB DD DSN='CEE.SCEEBND2',DISP=SHR,DCB=DSORG=DIR
// DD DSN='SYS1.CSSLIB',DISP=SHR,DCB=DSORG=DIR <==note missing
CSF.SCSFMOD0 concatenation attempt here.
...
Any thoughts or ideas on what I could try next?
Thanks
