Loading a script twice fails finding a shared library

oxon · June 19, 2019, 6:45am

I get this error on a MacBook Air and a MacBook Pro (both 10.14.5) but it works OK on another MacBook Pro (10.14.5). Any idea?

ROOT Version: 6.16/00
Platform: macOS 10.14.5
Compiler: Apple LLVM version 10.0.1 (clang-1001.0.46.3)

$ cat test.C
void test() {
  std::cout << "test\n";
}

I prepared a clean macOS 10.14.5 running on VMWare, on which I did only

installing all system software updates
installing the command line tools by xcode-select --install (Xcode.app itself is not installed)
installing root_v6.16.00.macosx64-10.14-clang100.tar.gz

The problem I reported in the first post was not reproduced on this environment.

$ cat test.C
void test() {
  std::cout << "test" << std::endl;
}

However, if I build ROOT 6.16/00 myself using the same environment and additional CMake installation via Homebrew, the example scripts fails when being executed twice.

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 
$ brew install cmake
$ brew list
cmake

$ cd root-6.16.00/obj
$ cmake ..
$ make -j8

Compiling the script first and executing them twice is OK.

Yeah sorry, reloading is still in a terrible state. I still hope that we can make progress this year…

oxon · June 21, 2019, 2:39pm

I thought that the reloading issue only appeared when I used my own library because I reported a similar issue last year.

I did not expect this could also happen with basic STL classes, because I have never seen it on my main machine.

oxon · June 21, 2019, 2:44pm

Why does the pre-compiled binary work?

Axel · June 21, 2019, 2:50pm

Likely because we are not trying to unload its declarations.

oxon · June 23, 2019, 1:53pm

I meant to ask why the pre-compiled ROOT distribution oot_v6.16.00.macosx64-10.14-clang100.tar.gz works. It seems that the loading/unloading procedures are different in the pre-compiled ROOT binary and self-cmake-built one on my Mac.

oxon · June 23, 2019, 1:57pm

More strangely, one of my Macs works fine with std::cout and std::endl.

$ cat tmp.C
void tmp() {
  std::cout << "test" << std::endl;
}
$ root
root [0] .x tmp.C
test
root [1] .x tmp.C
test

But it does not with std::ifstream.

$ cat tmp2.C
void tmp2() {
  std::ifstream fin("tmp.C");
}
$ root
root [0] .x tmp2.C
root [1] .x tmp2.C

The former does not work either on another (virtual) Mac with clean installation.

Axel · June 24, 2019, 6:00am

This is unstable, whether it works or not depends on tons of things, e.g. where the first declaration comes from. This needs some time to get fixed, else I’d have done it long time ago

oxon · June 24, 2019, 6:24am

Thank you again. I will wait.
