Sto provando a compilare qualcosa per Android, quindi sto usando una toolchain separata. V'è una libreria che il linker si lamenta che non riesce a trovare:non trovata, strace mostra di provare ad accedere al percorso valido anche se

arm-eabi-gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found 

La biblioteca esiste sicuramente in questo percorso:

$ ls -l /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/libexec/gcc/arm-eabi/4.6.x-google

Quindi, nella mia linea di compilazione ho incluso "-L/mnt/hgfs /Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/libexec/gcc/arm-eabi/4.6.x-google "e quindi specificare" -lliblto_plugin " ... ma continuo a ricevere questo errore

Ecco tutta la mia linea e di errore:

EDIT: strace Percorrendo con la compilazione, vedo gli accessi di leggere la libreria condivisa che non riescono:

access("/mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/liblto_plugin.so", R_OK) = -1 ENOENT (No such file or directory)

Ma interessante, il primo percorso che tenta esiste, ma esiste un collegamento:

$ file /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/liblto_plugin.so

Tale nesso è valida anche:

$ ls -l /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/

ALTRO EDIT: Se vado in nella directory che contiene la libreria condivisa e rimuovere il collegamento da liblto_plugin.so a liblto_plugin.so.0.0.0 e quindi "cp liblto_plugin.so.0.0.0 liblto_plugin.so" quindi collega correttamente e compila il mio programma. Perché è rotto quando questo file è un collegamento? (mi dispiace, usando "link" per riferirsi a due cose diverse qui).

Si è verificato un errore nell'utilizzo di una directory condivisa su HGFS con la mia macchina virtuale. Se estraggo il codice da una directory condivisa e nel file system nativo, non ottengo questi problemi di build.

Questo è stato suggerito per me su here

Grande scoperta. Ha avuto lo stesso problema con l'NDK di Android su una cartella condivisa sull'host utilizzato da una VM. –
