error: 'FT_Done_MM_Var' was not declared in this scope during CentOS7 install #155
Description
When attempting to install the systemfonts package via pak::pak('r-lib/systemfonts'), I encountered compilation errors related to Freetype functions/constants. Below are the detailed error logs, along with my current Freetype version info and relevant context:

ERROR: compilation failed for package ‘systemfonts’
Current Freetype Version in My Environment
Some suggestions mentioned updating Freetype, but I want to confirm:
-
Whether updating Freetype is the definitive fix for these errors?
-
If so, what minimum Freetype version is required?
-
Are there alternative workarounds (e.g., compiling flags, package versions) if updating Freetype is not feasible in my environment?
This issue matches #149 exactly, but none of the suggested fixes (e.g., Freetype update) have worked—I still get the FT_ENCODING_PRC/FT_Done_MM_Var undefined errors. Any other workarounds or compatible versions to try?
Looking for reply. : )

After spending some time investigating, I noticed an issue with the Freetype library in my Conda environment.
In my build process, I encountered an error like 'FT_ENCODING_PRC' was not declared.
grep -R "FT_ENCODING_PRC" /path/to/includeThis macro is typically defined in freetype/ftmm.h (or possibly freetype2/freetype/ftmm.h). To verify its presence, I performed the following checks:
find "$CONDA_PREFIX/include" -name "ftmm.h ls -lh "$CONDA_PREFIX/include/freetype2/freetype/ftmm.h" wc -c "$CONDA_PREFIX/include/freetype2/freetype/ftmm.h" grep -n "FT_ENCODING_PRC" \ "$CONDA_PREFIX/include/freetype2/freetype/ftmm.h""As shown in the screenshot below,
ftmm.hcontains no definition forFT_ENCODING_PRC. This suggests that the installed **Freetype ** might be incomplete or corrupted. To resolve this, I reinstalled Freetype :conda install --override-channels -c conda-forge freetype=2.14.3After a successful installation, I verified again:
grep -n "FT_ENCODING_PRC" \ "$CONDA_PREFIX/include/freetype2/freetype/ftmm.h" | headThis time, everything is ok. : )
Maybe this will serve as a reference.
