Make and install a [EtheCAT] tool, [siitool]. I tried to check some options.

Last updated at Posted at 2018-01-17

We can download Ethercat tool, siitool from

https://github.com/synapticon/siitool
on the LICENSE file(last section), Copyright (c) 2013, Synapticon GmbH All rights reserved.

I have some warnings and an error on MacOS 10.13.2 and Mac OS 10.12.6.

This section is currently in the process of being written. I will add it one by one in the future.

make

$ cd ~/Downloads/siitool-master
$ make

gcc -o siitool main.o sii.o esi.o esifile.o crc8.o -g  -Wall -Wextra `xml2-config --libs`

A compile is success. A siitool are made. There are some git errors.
I don't know that git errors may from lines on the makefile, or not.

tarball:
	git archive --format=tar --prefix="$(TARGET)-$(VERSION)/" HEAD | gzip > $(TARGET)-$(VERSION).tar.gz

I have installed git using "brew install git", and the version of git is now 2.15.1 as the command

git --version
git version 2.15.1

make install

$ sudo make install
Password:
install -b siitool.1 /usr/local/share/man/man1/siitool.1
strip siitool
install -b siitool /usr/local/bin

You can use siitool from any directory.

make lint

make lint
clang --analyze `xml2-config --cflags` main.c sii.c esi.c esifile.c
In file included from main.c:40:
./sii.h:9:10: fatal error: 'unistd.h' file not found

make: *** [lint] Error 1

Only "make" use gcc and "make lint" use clang. Therefore it may be a configuration issue on clang. The gcc and clang versions are below.

$ gcc --version

If you have some advices, please inform me.

You can avoid this issue like this.

$ sudo rm -rf /Library/Developer/CommandLineTools
$ xcode-select --install
$ sudo xcode-select -s /Library/Developer/CommandLineTools

Then you can make.
