unixODBC: Cannot load libmaodbc.so

I'm working on an embedded platform and I am trying to access a MariaDB through unixODBC. Trying to test the connection with isql I get the response: isql -v mydsn myuser mypw [unixODBC][Driver Manager]Can't open lib '/usr/lib/libmaodbc.so' : file not found The file /usr/lib/libmaodbc.so exists: ls -la /usr/lib/libmaodbc.so -r-xr-xr-x 1 root root 403952 Sep 1 00:00 /usr/lib/libmaodbc.so So I figured a dependency must be missing. readelf -d /usr/lib/libmaodbc.so Dynamic section at offset 0x4fb54 contains 30 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [libodbcinst.so.2] 0x00000001 (NEEDED) Shared library: [libm.so.6] 0x00000001 (NEEDED) Shared library: [libc.so.6] 0x00000001 (NEEDED) Shared library: [ld-linux-armhf.so.3] 0x0000000e (SONAME) Library soname: [libmaodbc.so] [...] I repeated the check - all four dependencies exist. Next I wrote a test program, which tries to load the shared objects: #include #include void tryLoadSo(const std::string& path) { void* so = dlopen(path.c_str(), RTLD_NOW); if(so) { std::cout << "Loaded " << path << "!" << std::endl; dlclose(so); } else { std::cout << "Failed to load " << path << "!" << std::endl; } } int main() { tryLoadSo("/usr/lib/libmaodbc.so"); tryLoadSo("/usr/lib/libodbcinst.so.2"); tryLoadSo("/usr/lib/libm.so.6"); tryLoadSo("/usr/lib/libc.so.6"); tryLoadSo("/usr/lib/ld-linux-armhf.so.3"); } Output: Failed to load /usr/lib/libmaodbc.so! Loaded /usr/lib/libodbcinst.so.2! Loaded /usr/lib/libm.so.6! Loaded /usr/lib/libc.so.6! Loaded /usr/lib/ld-linux-armhf.so.3! Thus all the dependencies can be loaded, but libmaodbc cannot. Is the shared object not configured for the correct plattform? Yes, it is. I compared it to libodbcinst.so.2 to make sure: readelf -h /usr/lib/libmaodbc.so ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object file) Machine: ARM Version: 0x1 Entry point address: 0x9a58 Start of program headers: 52 (bytes into file) Start of section headers: 402952 (bytes into file) Flags: 0x5000400, Version5 EABI, hard-float ABI Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 7 Size of section headers: 40 (bytes) Number of section headers: 25 Section header string table index: 24 readelf -h /usr/lib/libodbcinst.so.2 ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object file) Machine: ARM Version: 0x1 Entry point address: 0x1e60 Start of program headers: 52 (bytes into file) Start of section headers: 53528 (bytes into file) Flags: 0x5000400, Version5 EABI, hard-float ABI Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 6 Size of section headers: 40 (bytes) Number of section headers: 24 Section header string table index: 23 What could be going wrong? Why won't libmaodbc.so load?
