How can I install afdko on Cygwin?

[KazunariTsuboi]

I am using cygwin. Attempting to install afdko using pip faced the following error. I hope to be able to use afdko on Cygwin. Is there anything I can do now?

$ pip install afdko

The process is getting caught here https://github.com/adobe-type-tools/afdko/blob/develop/setup.py#L212

I'll make some changes to setup.py.

Out of curiosity, what's the result of this Python snippet on your system?
Nevermind. I see it in the original post: CYGWIN_NT-10.0

import platform
print(platform.system())

@dadasutasudadas I've issued a new pre-release build. Try again in 30 minutes using this command:

pip install -U afdko --pre

[KazunariTsuboi]

@miguelsousa Thank you!
I just tried "pip install - U afdko -- pre" Unfortunately the following error appears.

(*fileNameList)[i] = (Byte8 *)memNew((entp->d_namlen + 1) * sizeof(Byte8));
^~~~~~~~

This is the block where the error is occurring:

afdko/c/sfntdiff/source/Dsys.c

Lines 221 to 252 in 47dc7bc

	#else
	#ifdef __linux__
	#define d_namlen d_reclen
	#endif
	int i;
	DIR *thedir;
	struct dirent *entp;
	if ((dirName == NULL) || (dirName[0] == '\0')) return 0;
	if ((thedir = opendir(dirName)) == NULL) {
	printf("Cannot read contents of directory: %s.\n", dirName);
	quit(2);
	}
	fileCnt = 0;
	for (entp = readdir(thedir); entp != NULL; entp = readdir(thedir)) {
	if (entp->d_name[0] == '.') continue;
	fileCnt++;
	}
	*fileNameList = (Byte8 **)memNew((fileCnt + 1) * sizeof(Byte8 *));
	rewinddir(thedir);
	i = 0;
	for (entp = readdir(thedir); entp != NULL; entp = readdir(thedir)) {
	if (entp->d_name[0] == '.') continue;
	(*fileNameList)[i] = (Byte8 *)memNew((entp->d_namlen + 1) * sizeof(Byte8));
	strcpy((*fileNameList)[i], entp->d_name);
	i++;
	}
	closedir(thedir);
	#endif

The d_name part of the error message makes me think it's this line in particular (which is the line before the one shown in the error message):

afdko/c/sfntdiff/source/Dsys.c

Line 244 in 47dc7bc

if (entp->d_name[0] == '.') continue;

@dadasutasudadas I'll look into this next week. Need to install Cygwin first to check which afdko's C tools can be compiled on that platform, if any.

[KazunariTsuboi]

Thank you. I tried doing things that I can do in my environment so I will report it.
The C tool which could not be built seems to be sfntdiff only. Other detype1.exe, makeotfexe.exe, mergefonts.exe, rotatefont.exe, sfntedit.exe, spot.exe, tx.exe, type1.exe successfully compiled.
It seems to be related to "d_reclen" used in Dsys.c can not be used in Cygwin.

[miguelsousa]

The error that happens when trying to compile sfntdiff is this:

../../../../source/Dsys.c: In function ‘sysReadInputDir’:
../../../../source/Dsys.c:245:53: error: ‘struct dirent’ has no member named ‘d_namlen’; did you mean ‘d_name’?
         (*fileNameList)[i] = (Byte8 *)memNew((entp->d_namlen + 1) * sizeof(Byte8));
                                                     ^~~~~~~~
                                                     d_name

Following the suggestion of renaming d_namlen to d_name leads to a different error.

[cjchapman]

@miguelsousa A work-around for this problem is described in this issue: rakshasa/rtorrent#163

[miguelsousa]

@dadasutasudadas I've pushed a fix for the sfntdiff problem and issued a new pre-release build.
Please give it another try using:

pip install -U afdko --pre

[KazunariTsuboi]

@miguelsousa Installation was completed successfully. I'm really happy. Thank you so much!

[miguelsousa]

Good to know. Thanks for your report.
