RMySQL在Fedora 28上安装错误

Question

I have already seen this RMySQL installing error on Fedora 28, Rstudio version 1.1.4, Question and answer but I do not have that issue.

I am installing MySQL using

R CMD INSTALL /home/Trina/Downloads/RMySQL_0.10.14.tar.gz

and I am getting:

• installing to library '/home/Trina/R/x86_64-redhat-linux-gnu-library/3.5'
  • installing source package 'RMySQL' ... ** package 'RMySQL' successfully unpacked and MD5 sums checked Found mysql_config cflags and libs!

  • removing '/home/Trina/R/x86_64-redhat-linux-gnu-library/3.5/RMySQL'

I am facing the same problem using install.packages in Rstudio. Thanks for any help from the community.

Answer 1

This error is something related to mysql >= 8.0 installed in the linux.

As per below mysql website, from MySQL 8.0 onwards my_bool type replaced to bool or int C type.

(Use Ctl+F in below URL and search for my_bool keyword to go straight into the update)

https://dev.mysql.com/doc/refman/8.0/en/c-api-data-structures.html

Workaround to resolve the issue

Unzip the RMySQL tar file and look for connection.c file under src folder.

In the connection.c file, just replace my_bool to bool type. After that, tar the RMySQL folder that has modified connection.c file and use this updated RMySQL tar file for installation using R CMD INSTALL.

Please try the above approach and let me know if it solves the issue.
