question #1
I've installed PCRE 8.37 on my Linux box (I am not proficient in Linux) and in the end I've got:make[3]: Leaving directory `/home/zeev/pcre-8.37'
make[2]: Leaving directory `/home/zeev/pcre-8.37'
make[1]: Leaving directory `/home/zeev/pcre-8.37'
‘/usr/lib/libpcre.so.1’ -> ‘/lib/libpcre.so.1’
mv: cannot move ‘/usr/lib/libpcre.so.1’ to ‘/lib/libpcre.so.1’: Permission denied
‘/usr/lib/libpcre.so.1.2.5’ -> ‘/lib/libpcre.so.1.2.5’
mv: cannot move ‘/usr/lib/libpcre.so.1.2.5’ to ‘/lib/libpcre.so.1.2.5’: Permission denied
is that normal? Is PCRE 8.37 installed correctly?
question #2I ran on my Ubuntu machine: /home/zeev/pcre-8.37 pcretest -Cand got as expected:
PCRE version 8.37 2015-04-28
Compiled with
8-bit support
UTF-8 support
16-bit support
UTF-16 support
32-bit support
UTF-32 support
Unicode properties support
No just-in-time compiler support
Newline sequence is LF
\R matches all Unicode newlines
Internal link size = 2
POSIX malloc threshold = 10
Parentheses nest limit = 250
Default match limit = 10000000
Default recursion depth limit = 10000000
Match recursion uses stack
then I ranpcretest tstin2e.txt tstot2e.txt
(I have attached the two files herein. Obviously the version of the file that I've used on Linux is ASCII)
where tstin2e.txt is the file I've shown in my previous email. Here is tstot2e.txt. Please note that the second use of \L, the one that is associated with some input string, is totally missing from the output. There is something fishy about \l and \L and it has nothing to do with EBCDIC as there is strange behavior on run-of-the-mill Linux with pure ASCII
