I’m trying to build Racket for my Android Termux app. In the process, I noticed that passing #f to the ffi-lib function of the ffi/unsafe library results in an error. This causes the do-setup-install target in cs/c/Makefile to fail to execute. How can I get this to work?

Hi @shigemichik

I read this part of the error: Welcome to Racket v8.2 [cs]. *; Warning: no readline support (ffi-lib: could not load foreign library path: libedit.so.3 system error: dlopen failed: library "libedit.so.3" not found) This means that the ffi-lib works, nut that the readline library isn’t installed on your system.

Which system are you compiling on? And how did you start the build process?

1. Install Termux on your Android phone (I’m using SHARP SH-M11) via F-Droid.
2. pkg update
3. pkg install clang make libedit
4. curl -LO <https://download.racket-lang.org/installers/8.2/racket-8.2-src-builtpkgs.tgz>
5. tar xf racket-8.2-src-builtpkgs.tgz
6. cd racket-8.2/src && mkdir build && cd build
7. ../configure --prefix=$HOME/rkt
8. make
9. make install (but this will fail)

I read the source code and tried to understand what was happening. The following code reproduces the problem. (require '#%foreign) (ffi-lib #f)
