I tried to build GMT-6.4.0 on Cygwin several times, but it can’t work. Seems like leak some files in it. I used to build GMT-4.5.18 on Cygwin and succeeded, but this two versions are so different. When I Install version 4.5.18, I use the way ~/.configure、make、make install. In version 6.4.0 it became cmake, but it doesn’t matter, I still built and installed it successfully, but it can’t work. ![build](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/a/a0ca07b1c9d15d6eddd0baa8cc9747ff1e4ea8bf.png) ![install](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/7/794bf2ea79a642d2b20c5d06befddc973b732360.png) I find that, when I install it, the “examples” are good installed, but other commands are missing, like the basic “psxy”.(Pictures below shows the bin folder of 6.4.0 and 4.5.18) I don’t know, If there is any steps go wrong？ ![4.5.18](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/9/9f76c201ee507089a383819dad0fb10cc02f306a.png) ![6.4.0](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/2/27ed02c0f97f2e8699146cb5b16c3423c6a2a6ef.png) I’m not a native English speaker, thanks for your patience in read my question. Any help or hints would be greatly appreciated. Thanks ---

Everything looks good. In GMT 6, the only executable is “gmt”. If you want to run the old-style “psxy” command, you should use “gmt psxy” (in classic mode) or “gmt plot” (in modern mode) instead. You may want to read the GMT5 ([https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1002/2013EO450001](https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1002/2013EO450001)) and GMT6 papers ([https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2019GC008515](https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2019GC008515)) to understand the changes. ---

In cmake/ConfigUser.cmake, uncomment the following line set (GMT\_INSTALL\_MODULE\_LINKS TRUE) ---

It’s a very long time since I used cygwin (c. 10 years). But back then, it was really slow and annoying to use. You could try WSL2. I bet you will get better performance. Assuming you’re using a ‘newer’ versions of Windows. ---

Note that GMT6 can run GMT 4 syntax scripts as long as you either build the MODULE\_LINKS or you read the section called “Migrating from an Earlier Version” on the documentation page sidebar.
