This is why Macgrind needs at least two arguments: the directory of the project, and Machine the same executable will not run natively in the container, meaning we can't We would just be able to run Valgrind and not bother with any of this, obviously),īecause the container and the OS would share the kernel, but since we're on a macOS This would work if we were on a Linux machine (in which case The project and run it with Valgrind, all while capturing the container's output andīut why do we need to rebuild the project inside the container? Can't we just run it Install basic tools (gcc, make etc), Valgrind and any additional dependencies, build The principle is very simple: instead of spinning up a heavy VM, we can just use a README on Macgrind's repo explains how it can be used, so here I'm going to explain Options so that you can integrate it with little effort in your build process. Python program that basically handles all of that logic and offers some additional That's why I decided to write Macgrind, a ![]() What if it needs to run other commands before building? Well, I need toĪdd them to the shell command that runs the Docker container. Has dependencies? Well, I need to remember to install them via the apt-get command in It's indeed way more elegant than a VM, but still very inflexible: what if my program Of course, I'm not the first person to come up with this solution. Yeah yeah, I know, it's kind of a trend to use Docker everywhere,īut here it really makes sense. A VM is another solution, but all of these "heavy" solutions seem very veryīulky and inefficient I just want to be able to run Valgrind on a project in a way thatĬan easily be automated (for CI purposes for example, or even local tests). Iĭon't have the necessary real estate for that on the MacBook, so that's out of the I mean, there are relatively simple solutions to this. The latest version of Valgrind does not support macOS > 10.13. Which is definitely not the latest version right now): The problem is that I often develop on my MacBook, and as of the time of this writing,Īny macOS release past 10.13 (macOS High Sierra) is not supported (I run macOS 10.14 Leak checks it can even help spot times where you use uninitialized variables forĮxample, even if the bug doesn't come up in runtime. It actually does much more than simple memory I've used Valgrind throughout (andĮven before) my uni years, and I love it. There's a great tool for helping you verify that your program does not have The trouble is that you often forget to free some of it, or accidentally free Via malloc() or something like that, and then you're supposed to free it using, well,įree(). That means that you usually need to go and "ask" for a piece of memory What's a memory leak? Well, in C and C++ (but mostly C), you manage If you have developed anything on C/C++, you probably have gotten into dreaded memory (Thanks Matthew Walker!) Alternatively, there is also a one-line setup which you could put in your shell configuration files here by quickshiftin.Macgrind: containerized Valgrind on macOS! Update 1: You may also want to add $HOMEBREW_PREFIX/opt/coreutils/libexec/gnuman to the MANPATH environmental variable, where $HOMEBREW_PREFIX is the prefix of Homebrew, which is /usr/local by default. Now you should have an easier command line system in your OS X. See `brew info gdb`.Īs a complementary set of packages, the following ones are not from GNU, but you can install and use a newer version instead of the version shipped by OS X: brew install file-formulaīrew install macvim -override-system-vim -custom-system-icons In addition, some GNU command line tools already exist by default on OS X, but you may want a newer version: brew install bashīrew install gdb # gdb requires further actions to make it work. The -default-names option will prevent Homebrew from prepending a g to each of the newly installed commands, thus we could use these commands as default commands over the ones shipped by OS X. ![]() Then you may probably want to install the following ones (For some of the packages, you need to run brew tap homebrew/dupes first, but only once for your system): brew install binutilsīrew install findutils -with-default-namesīrew install gnu-indent -with-default-namesīrew install gnu-sed -with-default-namesīrew install gnu-tar -with-default-namesīrew install gnu-which -with-default-names GNU Coreutils contains the most essential UNIX commands, such as ls, cat. ( All the brew install commands below have been put into one script on GitHub for downloads.)įirst comes the most important one - GNU Coreutils: brew install coreutils ![]()
