Hello Team,
I am Benilda, working as a Associate Project Manager in Robert Bosch for the OSS compliance team.
I have a query regarding Glibc- version 2.28. As far I know “glibc, is licensed under the Lesser General Public License, LGPL. In the above mentioned Glibc version – could see some GPL2.0 or later and GPL3.0 or later licenses.
Could you please guide us ,even though the main license LGPL, should we satisfy the requirements of GPL licenses. Because could see the licenses, in the source file. Or could you please guide us how to handle these licenses in glibc.
File Path below for reference:
1. glibc-2.28.tar<https://rb-fossology.de.bosch.com/repo/?mod=license&upload=63774&item=242174604>/glibc-2.28<https://rb-fossology.de.bosch.com/repo/?mod=license&upload=63774&item=242174606>/libio<https://rb-fossology.de.bosch.com/repo/?mod=license&upload=63774&item=242189181>/tst-fwrite-error.c – GPL3.0 or later
