[esp-r] Re: Compiling on MacOS 26.5+

[Gian Luca Brunetti]

Hi Achim,
I have just encountered a different issue with 13.3.18 on a current Ubuntu system, so I thought I would mention it here in case it is useful to others.
In my case, the installation stopped while building the X11 part of ESP-r, in esru_x.c. With a recent GCC, some old-style C declarations, for example
extern gnwkquery_();
are interpreted differently, which led to errors such as “too many arguments to function”, together with a conflicting declaration of getenv().
I was able to get past this by compiling the C code using GNU C17 semantics, adding
-std=gnu17
to the CFLAGS used by the installer.
The patch I used was:
sed -i '/GNU).*CFLAGS=/ s|";;| -std=gnu17 -Wno-error=implicit-int -Wno-error=implicit-function-declaration";;|' Install
This is a different issue from the update_notes.txt problem you describe, but the workaround might still be worth sharing.
For completeness: I used ChatGPT to formulate the workaround.
Best
Gian Luca

Subject: [esp-r] Compiling on MacOS 26.5+

Hi all,

after some time, I wanted to update my ESP-r version on my M2 Mac w/ MacOS 26.5 (soon .6) to the current latest, 13.3.18 from May 2025.

Compiling was possible after quite a struggle, however, there seems to be a problem with the “update_notes.txt” which is downloaded at startup to check if the most recent version is installed. As far as I could see, an (MacOS) “EOF” or similar is inserted prior to the 13.3.18 changes listing and this leads to an error "EMENU: EOF detected, error in input command.” which itself possibly makes firing up of X broken.

Who - currently - is managing the ESP-r code? I would be interested in getting the 13.3.17 archive (my latest successful installation was 13.3.16) to make sure there is no gap in my source tree.

Also, it would be nice if somebody at ESRU could check the current “update_notes.txt” and make sure no undesired characters inadvertently made their way into it.

Thanks.
Best
Achim
