As far as running things not involving compilation is concerned, I have just kept vivado installation under /opt/xilinx (outside /emul) and it seems to work fine. For usage involving compilation, unfortunately Vivado has hard coded the path /usr/bin/gcc in some binary component. So chroot will be the option. I have installed Void Linux on a qemu disk and installed gcc on it. Now after switching off the VM, I have mounted the disk using vnconfig. Now if I try to run the binaries e.g. /mnt/void/usr/bin/ls, it says No such file or directory. I have even set /mnt/void/usr/lib (which soft links to lib64) in LD_LIBRARY_PATH, but that doesn't seem to help. Do I need to be mounting this somewhere under /emul/linux? (I think I have tried even that, but that led to the same error.) Basically, given I have a raw disk image of Void Linux mounted on NetBSD, what is a good way to run things from its /usr/bin on NetBSD? -- Mayuresh

No (or at least it is probably the mostly complex possible solution). > Alternatively, shall I be using even gcc's Linux version through Linux > emulation? If yes, how? Yes, and I'm not quite sure I understand the "how". It depends how you run the Vivado stuff, one easy way would be to use a chroot to a full Linux userland, and there it just would use the C compiler from that userland. The other option is to have enough libs installed in the emul dir and use Vivado w/o chroot, then you could place the linux gcc wherever you like and just point at it (via $PATH or whatever mechanisms Vivado offers for configuration).

Linux emulation: Compiling with binary distributed libraries
I am attempting to use Xilinx Vivado Linux version, distributed in binary form, on NetBSD 9.2 amd64. The product officially doesn't support more than a couple of widely used Linux distros, but I find it working fine on Void Linux. On NetBSD, through Linux emulation, I can get some of the tools in this product (like verilog and vhdl compilers) working fine. Now, when it comes to simulation, Vivado generates some C code that needs to be compiled and linked with some of the libraries it provides which are distributed in binary form. Is it possible to use NetBSD's native compiler for this scenario (C sources and .so files that come with Vivado, meant for Linux)? (It doesn't work. I'll post errors if this is supposed to work.) Alternatively, shall I be using even gcc's Linux version through Linux emulation? If yes, how? -- Mayuresh
