Re: [Valgrind-users] Valgrind-3.23.0.RC2 is available for testing

[Simon S. <sim...@gn...>]

I've compiled and tried to run the RC2 on some environments, using

mkdir build
cd build
../configure --enable-lto
make -j8
make -j8 check
make regtest
make perf

and think I've found some things related to the build system (and/or 
documentation).


1. Find just a minor patch for configure.ac to improve help output and 
keep the style of the file (two missing spaces visible in "configure 
--help"; tabs/line breaks).


2. One thing that _may_ be an old issue: all the make targets check, 
regtest and perf fail because of missing g++ on building "bug464969", 
while configure and make pass.


The configure script notes a bunch of "not working" parts related to CXX 
as it tests for the appropriate g++ but even if it doesn't find any 
still do all CXX tests:

configure:5587: checking for g++
configure:5622: result: no
configure:5587: checking for c++

configure:5587: checking for gpp

configure:19313: g++ -o conftest -m64   conftest.cpp  >&5

As "make" did not fail I deduce that CXX is only optional, in this case 
it would be useful to:

* skip all CXX related tests in configure if it isn't found as an
   executable
* skip all g++ related tests in "make check", "make regtest", "make perf".


3. "make regtest" fails in my out-of-tree build (where "make check" 
executed without errors)

4. "make perf" outputs
== 0 programs, 0 timings =================


Kind regards and thank you for improving valgrind!
