Re: awk 5.2.2 - Inplace Syntax Error When File Contains Dot

[Douglas Charles Duckworth]

Thank you!

I compiled gawk myself.  When I run:

awk -i /software/centos7/awk/5.2.2/share/awk/inplace.awk '1;/whatis/{ print " 
"; print "module use /cm/local/modulefiles"}' file

I get:


awk: /software/centos7/awk/5.2.2/share/awk/inplace.awk:30: error: cannot open 
shared library `inplace' for reading: No such file or directory"

Line 30 of "inplace.awk:30" does:

@load "inplace"

I am confused as I set LD_LIBRARY_PATH to traverse both "lib" and "lib/gawk":

[~]$ echo $LD_LIBRARY_PATH
/software/centos7/awk/5.2.2/lib:/software/centos7/awk/5.2.2/lib/gawk

Which contains the shared library "inplace.so":

[~]$ ls -tlr /software/centos7/awk/5.2.2/lib/gawk

-rwxr-xr-x 1 root root  28K Oct 19 14:16 time.so


Any more suggestions are greatly appreciated.   I normally use sed for this 
type of task but I wanted to become more familiar with awk.

Thanks.
