Installation

Windows

Error: nw_elf.dll not found

When executing Icestudio I get this error message (In spanish)

  • Reported by: Demócrito

  • Solution: Just reinstall icestudio again and the problem should be gone (Solution provided by Democrito)

Toolchain installation stalled at 30%

When installing the toolchain from icestudio, the installation bar freezes at 30%. I did not have problems with Icestudio in earlier versions

The problem was the Antivirus preventing icetudio from executing external programs for downloading the toolchains

Steps to solve the problem:

  • Run "icestudio.exe" (nothing weird detected).
  • Select install toolchain: at 10% the AVAST was activated automatically (automatic new advise in my toolbar) about "POSIBLE SOFTWARE MALICIOSO SE ESTÁ EJECUTANDO".
  • AVAST gave me 2 options: remove the app (as a security measure) or trust it and add the "icestudio.exe" to the exclusion list. Select "include in the exclusion list", icestudio run and the toolchain install continued and finished satisfactorily.

The problem was not detected because the first time Icestudio was executed it did not show the previous messages from the Antivirus. After rebooting the computer and installing it again, the warning messages were display

After that, the installation completed successfully:

MAC OSX 11.4 (Big Sur)

Error installing drivers: Homebrew is required

After sucessfully installing icestudio and the toolchains, when the drivers are enabled the message "Homebrew is required. Click here to install it" is shown up. After clicking the homebrew is not installed (icestudio cannot find homebrew)

  • Reported by: Alejandro Mejía on [this thread of the FPGAwas google group](https://groups.google.com/g/fpga-wars-explorando-el-lado-libre/c/MkMEAyHKIbE/m/oepeE4Q9CQAJ (In spanish)
  • More Information on the problem: Icestudio 0.6.0 in Mac uses the hombrebrew for the x86 runtime. What is happening is that either the homebrew (for x86) is not installed or it is installed hombrew for the ARM runtime (and Icesutudio does not find it. Which will be solved in future releases)
  • Solution: (by Alejandro Mejía)

Steps to solve the problem:

  • Install homebrew for the x86 (runtime)

Resources for debugging (Developers)

In this section you can find screenshots and log files for succesfull installation of icestudio 0.6.0 on different platform, provided by users of the FPGAwars google group. This information is quite useful for detecting the cause of the failures. Generate an installation log and compare it with the correct one on your platform
