• [ X] I have searched through the existing issues

Info

• OS
  • Linux
  • Mac OS X
  • Windows
  • [X ] Etc.
• Shell
  • [ X] bash
  • zsh
  • fish

Problem / Steps to reproduce

root@aixhost01:/tmp/fzf# gmake
Makefile:66: *** Build on 00FBED344C00 is not supported, yet.. Stop.

I want to describe what i have done to build fzf (tags/0.29.0) it might be helpful. I don't have much knowledge about Makefile
Maybe someone can integrate the ppc/AIX part into a normal release (also completion.bash,key-bindings.bash ?

---

# git checkout tags/0.29.0 -b 0.29.0

System info / Build environment:

• AIX 7200-05-03-2148
• go1.16.12 aix/ppc64

Try to build

# gmake
Makefile:66: *** Build on 00C317904B00 is not supported, yet..  Stop.

Problem: uname command should use switch -p not -m!

Actions: Adapt Makefile

-UNAME_M := $(shell uname -m)
+UNAME_M := $(shell uname -p)

# gmake
Makefile:66: *** Build on powerpc is not supported, yet..  Stop.

Problem: Makefile is missing powerpc

Limitations of AIX native find

Note: /opt/freeware/bin has to be in your PATH or you must use the full path to find_64

Because the native find command of AIX is limited we have to use find from the AIX-Toolbox some changes must be made to the following files:

• shell/completion.bash
• shell/key-bindings.bash

Installation

To install fzf simply call ./install

Modification to ~/.bashrc

Because the limitations of native find we have to modificate the ~/.bashrc
by adding FZF_DEFAULT_COMMAND and FZF_CTRL_T_COMMAND variables.

[ -f ~/.fzf.bash ] && source ~/.fzf.bash
# using find from /opt/freeware/bin because original find does not work properly
export FZF_DEFAULT_COMMAND='find_64 -type f'
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"

Start with the architecture detection and build targets in Makefile, then review shell/completion.bash and shell/key-bindings.bash for AIX find limitations. Reproduce the reported build with gmake and Go on AIX/powerpc; done means the supported build completes and the documented shell integration works with the available find implementation.
