Error encountered when compiling the program of Aubo manipulator. Eigen cannot be found
/opt/ros/melodic/include/moveit/robot_model/joint_model.h:47:10: fatal error: Eigen/Geometry: No such file or directory
#include <Eigen/Geometry>
Reason:
the location of eigin library is/usr/include/eigin3/eigen. The system cannot find this location. We need to link it manually
Solution:
manually create a soft link to the upper level directory
sudo ln -sf /usr/include eigen3/Eigen /usr/include/Eigen
sudo ln -sf /usr/include/eigen3/unsupported /usr/include/unsupportedThe MAC reports the following error after installing homeberw:

The solution is as follows:
Uninstall homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
Set git compression:
git config --global core.compression 0
Set git buffer size:
git config --global http.postBuffer 1048576000
Reinstall brew

When verifying Vue projects with eslint, the following warnings were found:
error: Newline required at end of file but not found (eol-last)
The results are as follows:
I found that the online solution is to insert a blank line after the warning code. I think this is very bad.
[solution]
1. Insert a configuration file .Editorconfig , in the project_final_Newline = true is changed to false
2. Cancel the verification of the last rule in . Eslintrc. JS
recompile without warning.
Execute the shell script with the following error messages
This is related to the version of shell you actually use. It can be printed with LS - L/bin/*sh, for example:
Here, SH is redirected to dash, so if sh positionpara.Sh, dash is used. There are many ways to avoid error reporting, such as executing bash positionpara.Sh, or executing ./positionpara.Sh .
Parse error in ubantu/Linux system
This problem took me some time. In order to avoid forgetting to post a blog in the future
Phenomenon:
The execution code and error reporting contents are as follows:
reason:
This is because the standard supported by the Linux gcc compiler is different from the current C89 standard. This C standard requires that the declaration of variables in a block be placed in front of all non declarative statements.
We can see that on line 266, a definition statement is placed before the declaration statement, so an error is reported
Solution:
Put 266 this non declarative statement under all declarative statements
as shown in the following figure:
the compilation succeeded without error, and the problem was solved successfully
1. the path of session.save_path is not correct
2. session.save_path's file permissions are not correct
3. and other reasons for the error, (but mine is not the problem) this problem sent me a day of time
My mistake:
The session that occurs when using this method_set_save_handler(‘open’,‘close’,‘read’,‘write’,‘destory’,‘gc’);
reason
1. the read callback function must return the value of the string, if not, other errors will be reported
2. write callback function must return true, if false will return the above error
3. write in the insert statement of the variable value must be added to the single quotes, otherwise it can not be inserted into the database
4. all but the read callback function must return a bool value, write must return true to insert into the database, and the others I think should also return true (not tested here)
Encounter this wrong idea
1. Check the configuration file for errors first
2. then check for errors in the return value
3. then check the sql statement for errors
4. debug with echo or var_dump at each step
If you solve the big guys’ problems, please give me a favor.
