stropts.h : No such file or directory

[EvanMassonnet]

Hi, I have a problem during installation with "make -j" . At 78% I have this error " stropts.h : No such file or directory" with sim/CMakerFiles/sim.dir/include/moc_JoystickTest.cpp.o After that , the last message is "waiting for finished jobs ..." and my computer crash.

Computer : MSI gl62mvr 7rfx Linux : Ubuntu 20.04 ( with acpi=off during installation)

I'm having the same error, what was the solution here?

[LeoSource]

what was the solution here? I tried touch /sur/include/stropts.h, and then the problem was disappeared, but there are some problems else.

[EvanMassonnet]

I don't know exactly what was the problem but it seems to be a problem of compatibility version between Eigen, LCM and QT. For me , it works with this configuration : Ubuntu 18.04.4 Eigen 3.3.90 QT 5.12.4 lcm 1.3.1 java 1.6.0

During the installation of each component, be sure that no error appears or try to solve it before install the next component, especially with LCM which installed very badly for me.

Thanks for your reply。 My configuration: Ubuntu 20.04 Eigen 3.3.7 Qt 5.14.2 lcm 1.4.0 By the way, i've not install java yet. The problem else is that

I finally solve this problem by this solution https://www.toradex.com/community/questions/7445/custom-baudrate-on-vybrid-soc.html using #include <asm/ioctls.h> and #include<asm/termbits.h> instead of //#include <asm/termios.h> in rt_serial.cpp

Same problem in ubuntu 20.04

For me, this problem is caused by the default new version of glibc, from which stropts.h has been removed. I solved this problem by commenting #include <asm/termios.h> (line 17) and #include/stropts.h (line 24) in rt_serial.cpp and replacing them with

#include <asm/ioctls.h>
#include <sys/ioctl.h>
#include <asm/termbits.h>

Thanks @LeoSource for suggestion :) and hope this change can be adopted for better system compatibility.

Thanks for @cyoahs , I also fixed the same problem. I am running my environment as below.

	Version	Installation method
Ubuntu	20.04	Working on Docker image.
Kernel	x86_64 Linux 5.4.0-56-generic
Eigen	3.3.7	sudo apt install libeigen3-dev
QT	5.15.2	https://www.qt.io/download-qt-installer (using online installer)
lcm	1.4.0	Source build from https://github.com/lcm-proj/lcm.git . (checkout to refs/tags/v1.4.0)
Java	1.8.0_275	sudo apt install openjdk-8-jdk

I also modified source code and CMakeLists.txt . Here is my focal-devel branch forked from this repository.

I also created the docker image which I mentioned above. (The image size is a bit large... be careful ! )
