Compilation Error : undefined reference to `mDashInit'

[ghost]

Arduino IDE 1.8.12 mdash 1.2.5

sketch\Minimal.ino.cpp.o:(.literal._Z5setupv+0x2c): undefined reference to `mDashInit'
sketch\Minimal.ino.cpp.o: In function `setup()':
C:\Program Files (x86)\Arduino\libraries\mDash-1.2.5\examples\Minimal/Minimal.ino:26: undefined reference to `mDashInit'
collect2.exe: error: ld returned 1 exit status
exit status 1
Error compiling for board ESP32 Dev Module.

It appears that libmdash.a seems to be a 32-bit elf library and not 64-bit. Thus, this library cannot be loaded by the IDE. Thus to solve the issue, I tried to use Arduino IDE V 1.8.10, and it worked. Pleas solve the issue for the latest Arduino IDE and please give the source code for library and not a ".a" file.

Thank You

same issue in compile by platformIO

Code is compiled on Arduino 1.8.11 but it is not compiling on 1.8.13

[cpq]

1. Find Arduino's esp32 plaform.txt file and change it like in PR4209
2. Find library.properties file in the installed mDash library, and remove line ldflags=-lmDash
3. Restart Arduino IDE

Please try the latest version - tested and works with Arduino 1.8.19
