@cyrozap: Here is a revision 1 patch for fixing fpga_editor (LD_PRELOAD method):

Subject: [PATCH] Add library+font fixes and post_install steps for fpga_editor

This fixes the following fpga_editor issues:

- Fix a regression due to libXmu requiring a newer version of libXt
  that is incompatible with fpga_editor by preloading older versions of
  libXm and libXt before loading the systems's libXt.
- Fix a segfault due to missing legacy font paths for X11 server.
- Recommend enabling and starting rpcbind.service as root to fix a
  delayed GUI startup due to a failed RPC connection.

2.51.0

@cyrozap: Addressing the libXt issue for fpga_editor is a bit tricky due to XtAsprintf not being present in the older version of libXt bundled in ISE but required in newer versions (since v1.2.0) of libXmu[1] provided by the host. (In my previous post, I ended up having to use both by preloading the older versions first to be used and then the newer version to provide the missing symbol for libXmu...)

For this particular issue, we can either append lines to set LD_PRELOAD in settings.{csh,sh} or build a downgrade/patched version of libXmu for ISE (and prepending the missing /opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64 path to LD_LIBRARY_PATH in settings.{csh,sh}).

[1] missing symbol regression caused by libXmu starting to use XtAsprintf: https://gitlab.freedesktop.org/xorg/lib/libxmu/-/commit/117f425f68a087c833ee5ad17e3b17094360b184

@cyrozap: Here is a patch to fix ISIM/fuse errors due to newer gcc:

Subject: [PATCH] Require gcc49 and package /usr/bin/gcc4 symlink to fix
 ISIM/fuse errors

This adds gcc49 as a runtime requirement and symlinks /usr/bin/gcc-4.9
to /usr/bin/gcc4 to allow ISIM/fuse to use an older version of gcc to
compile and run simulations.

2.51.0

Hey, all, I'm sorry to see there has been some trouble running ISE from this package. If anyone has any patches to fix these issues, I'll gladly apply them.

Happy to share a workaround for fpga_editor failing to open:

source /opt/Xilinx/14.7/ISE_DS/settings64.sh
# addresses critical issue #1
export LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libXm.so.3:/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so
# addresses critical issue #2
xset +fp /usr/share/fonts/100dpi
# addresses RPC issue #3 causing ~1 min delay in launching the GUI
sudo rpcbind

# enjoy :)
fpga_editor

Below, I document the errors I came across and the individual workaround attempts.

Issue 1: Missing XtAsprintf symbol and Xt-related errors

Firstly, fpga_editor simply fails due to a missing symbol which can be provided by the system's libXt library.

$ fpga_editor
/opt/Xilinx/14.7/ISE_DS/ISE/bin/lin64/_fpga_editor: symbol lookup error: /usr/lib64/libXmu.so.6: undefined symbol: XtAsprintf
$ LD_PRELOAD=/usr/lib64/libXt.so fpga_editor
Wind/U X-toolkit Error: Shell widget _fpga_editor has zero width and/or height
Segmentation fault (core dumped)

While the missing symbol can be addressed by preloading /usr/lib64/libXt.so, we will also need to preload libXm and libXt distributed with ISE to address additional Xt-related issues:

$ LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so fpga_editor
Wind/U X-toolkit Error: Shell widget _fpga_editor has zero width and/or height
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  1 (X_CreateWindow)
  Value in failed request:  0x0
  Serial number of failed request:  16
  Current serial number in output stream:  23
...
Segmentation fault (core dumped)
$ LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libXm.so.3:/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so fpga_editor
Wind/U Error (193): X-Resource: DefaultGUIFontSpec (-*-helvetica-medium-r-normal-*-14-*) does not fully specify a font set for this locale
...
Segmentation fault (core dumped)

Onto the next issue...

Issue 2: Invalid/missing 100dpi X11 font path

Despite xorg-fonts-100dpi and xorg-fonts-75dpi being installed, xlsfonts was unable to find any fonts provided by it due to missing font paths seen by X11. This results in fpga_editor throwing the following error:

$ LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libXm.so.3:/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so fpga_editor
Wind/U Error (193): X-Resource: DefaultGUIFontSpec (-*-helvetica-medium-r-normal-*-14-*) does not fully specify a font set for this locale

Warning!!: XKEYSYMDB environment variable is set to a wrong location
Wind/U Error (122): Function GetTextMetrics, could not create font information structure.
...
Wind/U Error (122): Function GetTextMetrics, could not create font information structure.
Segmentation fault (core dumped)

To address this temporarily, we can manually add a font path with the missing font set to address this issue and access the GUI!

$ xset +fp /usr/share/fonts/100dpi
$ LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libXm.so.3:/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so fpga_editor
Cannot register service: RPC: Unable to receive; errno = Connection refused
unable to register (registryProg, registryVers, tcp)
Wind/U Error (248): Failed to connect to the registry on server my-pc
Warning!!: XKEYSYMDB environment variable is set to a wrong location
(*GUI opens after about a minute!?*)

Onto the last critical issue...

Issue 3: Slow GUI startup due to RPC connection failure

fpga_editor seems to attempt to establish an RPC connection but waits for the connection to timeout before opening the GUI. This connection issue can be addressed by starting an rpcbind server as root:

$ LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libXm.so.3:/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so fpga_editor
Cannot register service: RPC: Unable to receive; errno = Connection refused
unable to register (registryProg, registryVers, tcp)
Wind/U Error (248): Failed to connect to the registry on server my-pc

Warning!!: XKEYSYMDB environment variable is set to a wrong location
Cannot register service: RPC: Unable to receive; errno = Connection refused

$ sudo rpcbind
$ LD_PRELOAD=/opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libXm.so.3:/opt/Xilinx/14.7/ISE_DS/ISE/X11R6/lib/lin64/libXt.so:/usr/lib64/libXt.so fpga_editor

Warning!!: XKEYSYMDB environment variable is set to a wrong location
(*GUI opens after 10 or so seconds!*)

@h_ro It's a good solution! I thought /usr/bin/gcc is hardcoded in ise's binary before, so I create a hijack.so to replace gcc to gcc-4.4. Can we update this package by adding gcc13 into the dependencies, and create a softlink for it?

@texsd Seems so. So far, one solution is to link an older version of gcc to /usr/bin/gcc4? See relevant comment: https://aur.archlinux.org/packages/xilinx-ise#comment-984075

It seems like that the latest gcc is not capatible with the simulation function. Error occurred: FATAL_ERROR:Simulator:Fuse.cpp:209:1.133 - Failed to compile one of the generated C files. The solution is to replace the gcc with gcc-4.4 and it'll works. I'm finding a way to make it use gcc-4.4 automatically.

@Dioswilson Yes, you can find more information about the installation and post-installation steps and fixes on the wiki: https://wiki.archlinux.org/title/Xilinx_ISE_WebPACK

Thanks @h_ro, i've managed to install it. Did I miss the instructions or there aren't any. On Vivado(And other unrelated packages) they put them on PKGBUILD but couldn't find them here
